What is Real Time Data Communication ?
Real Time Data communication is same as live event, and Real Time Data Communication streams live data in any software or mobile app. It has to give a response in a specific time frame. In real time environment data has been received, processed and returned the final result in milliseconds or in microseconds. Today, many mobile app development companies have created apps that work on Real Time concept in the Current world. Example. Live Streaming Application, Stock Market Application, Chat Applications etc.
How it works ?
Real time applications are Client -Server - Client mechanism, in this the User is connected to both ends (Client and Server). Real Time is not only both way communication but it also has to perform in time which means the result of the communication has been done within the specified time frame. This process will not be called Real time if it is not performed within a specific time frame. Also, note that it is not necessary that every time Real time is high-performance computing.
Popular Third Party Real Time Options for Android
1. PubNub : PubNub is a Realtime Data streaming Network and Real Time Infrastructure as a service. This works on three core services Publish/Subscribe messaging pattern(which is also known as a Pub/Sub messaging pattern) , PubNub Functions and ChatEngine.
Publish/Subscribe messaging pattern: Sender of the message is called a Publisher and Receiver of the message is called a Subscriber
PubNub Functions: Basically functions allow us to run separate codes on PubNub Server side to handle message which needs to be streamed between the publisher and the subscriber.
ChatEngine: ChatEngine is a service to apply all the core feature of the Chat Quickly, it supports private and group chat.
2. Firebase Realtime Database and Cloud FireStorage: Firebase is an evolutionary mobile platform which is provided by Google. It gives us two options for managing Real Time data.
3. AWS AppSync: AWS AppSync interacts with data source using GraphQL (which is open standard query language) from your application.
AWS works on WebSockets which is a client/server web Technology, as compared to other libraries you have to handle the data by yourself which will add another layer of code from developer side.
Real Time Data Communication rushes live data through and in any software or mobile app. It is important because it has been designed to give the response in the specific time frame. There are many mobile app development companies that have created apps that work on Real Time concept in the Current world. 9series has solutions on the same for you.

As we all know following a procedure can be very boring, hectic and time-consuming in the development process. Most of the developers working in an iPhone app development company in India have the tendency to jump directly into the coding because of all the effects and fun there.
According to our experience in application development, it is very helpful to follow some practices before jumping into the coding part. It always helps in reducing complexity, increasing the readability, easier to maintain, avoiding redundancy, etc. Also, it is helpful to other team members to understand the concept and the flow of the application if working in a team.
So, let us check and dig the topics one-by-one which will be helpful to create a proper architecture of the application and also be helpful for the entire team in the future.
1. Define Coding Style
Coding Style is the most important aspect that should be defined before you start writing any application, especially while working in a team.
It includes the below points:
2. Define Architecture for The Application
It is necessary to decide the architecture for the app before diving into the code. Choice of suitable architecture will make the app more testable, easier to understand and reduce its maintenance cost. You can choose any architecture from traditional MVC to recent or fancier MVVM. There are so many resources available on the web from which you can understand and decide architecture for the application. Below is some reference for the design pattern. https://www.raywenderlich.com/132662/mvc-in-ios-a-modern-approach
3. Setup Folder Structure
Instead of keeping all the files in a single directory, it is a good idea to follow some folder structure for the project. It will make the files well organized and easily findable, you can use the following:
Although this may look negligible at the first sight but for the big projects, it is certainly more helpful, well structured and easier to understand for every team member working in the project.
4. Manage Your Dependencies
It is very certain that everyone is using some third party libraries in their application. So for that, you should use one of the dependency managers from the ones that are already available. We usually prefer CocoaPods which has the vast collection of libraries and easy integration facilities, you can use any of below depending on the requirements.
5. Setup Certificates and Profiles for Code Signing
Most annoying and painful task of the application development is creating certificates and provisioning profile. This process includes creating application id (Unique identifier for the device), adding devices to developer account, creating certificates (development certificate for debug the application and distribution certificate for releasing the application.), creating provisioning profiles (same as certificates), also creating APNS certificates if your application is willing to get the push notifications from the server, providing .pem file to PHP developers or .p12 file to .NET developers.
6. Continuous Integration
This is very much advisable either working in a team or individual. This will keep track of your development process and at any point of time, you can check the updates for the particular date or time period. You can use either git or SVN whichever is suitable for you for the continuous integration. This will help all the team members to pull the latest updates done by the other member as well as push the new changes to the other team members. The main benefit of this is you will have all your code on the server and you will be able to access it from anywhere.
7. Setting Application Icon and Splash Screen
Though this is not a mandatory task and not that much important for the initial stage but setting it initially make your application first impression good. Application icon carries a variety of sizes of the single image so instead of forcing designer for all size images you can just ask of 1024*1024 size icon with some background and you will be able to get all the required size images from some online or online tools. Splash screen set up is also carry 2 ways either you set the launch images or you can use the launch screen for setting up the splash screen.
In this article, we have covered the major points about defining the iOS Application development Architecture. Though list can be expanded more with more topics like how code style should be applied, commenting guide, etc. You can also add your own topics, thoughts, etc. and feel free to share with us.
We hope that these tips will be helpful for you to define and start the application with the best style.
Happy Coding! and feel free to share your own experience on “firstname.lastname@example.org”.

Hello everyone, as we all know that Share Extension is appeared from iOS 8, then the capability to share content with other entities, such as social sharing websites or upload services can be done in an easy and convenient way.
We, 9series, an iOS application development company has started doing all the development using Advanced Programming Language Swift.
So today, we are going to build a Shared Extension app in iOS10 with Swift 3.0, an ability to show an icon on the common share-sheet that associates with our main app, which handles the sharing of the content that the user has requested. So the user can easily switch from one app to another, for example, we are sharing a photo from the album with some content that switches our app where we want to upload data to the server.
This is mainly a programming article, so you are required to have Xcode 8 on Mac. Let’s get started !!!
1. Make a new Xcode Project
First Create a cocoa touch Single View Application in Xcode 8 with some basic UI. Like it is shown below
Design the screen with UILabel, UIImageView, UITextView and with UIButton. When user comes with some sharable content from parent app, we can upload or we can use anywhere in our app.
For Eg, let’s create the Share Extension.
Give some proper name of that extension and it will show you popup view for activating your extension scheme. Choose Activate to use this scheme for building and debugging.
Note: Schemes can be chosen from the toolbar or Product menu.
3. Make an App Group
We want to communicate two app for sharing some content, but Apple doesn't want a complete free flow of data between the two. Apple recommends a shared NSUserDefaults as a meeting ground where the two app can exchange their data.
Now, we need to make an app group.
Click on your project in the Navigator Pane of Xcode, click on capabilities and your app under the target list turns on App Groups. Give it a name like “group.BUNDLE IDENTIFIER”.
Now click on your extension and do the same.
4. Implementing Share Extensions in Swift
First open your viewController, we won’t go into much detail, because it's a destination viewController. So we can read content data from User Defaults which is shared by user from Share ViewController.
We have also created an IBAction of Upload button, so that content and photo which is shared by user can be used anywhere in our app.
Here, “sharedIdentifier” is the UserDefaults suiteName that we have used for the app group name. An extensionContext where we get a list of NSExtensionItems. This is a fixed array of data sent to our extension from a parent app. We are getting photo and content from our photos app that are already set to our main app.
Let's look at the “ShareViewController” from our Shared Extension Folder which is subclass of SLComposeServiceViewController. SLComposeServiceViewController has some methods and properties associated with the lifecycle of a share-sheet composition view.
isContentValid() :- It is called every time when the content in the compose view changes. Here, we can check the input data is valid or not. It is called first, and will disable the post button when it evaluates to false.
didSelectPost() :- As the name suggests, it is called when the user presses the post button. Here we can do something with the user input. Once the upload is scheduled, you must call completeRequestReturningItems(, completionHandler:) so that the host app can un-block its UI. When the upload request is done, it calls the completion handler that was passed into the previous mentioned function call.
configurationItems() :- Here, we can add more things for the user to select when they are sharing. In our case we are sharing a photo with contentText. You can also make it more dynamic with some other controls.
contentText :- A string which represents what the user has typed into the composer.
charactersRemaining :- Is a number which appears on the compose sheet. When negative number shows, its appearance becomes red.
Here is the code of “ShareViewController”
Here, we are selecting one image from photo album and then clicking on share button, it will open share sheet with our Share Extension app Icon.
Select that app and it will open composition view.
We have mentioned maximum characters of contentText as 100, so if you enter more than 100 characters, than it will generate alert message and post button will be disabled. You can also check number of characters at the end of compose sheet.
Configuration! items is where we can add more things for the user selection, when they are sharing. Like, Open UITableViewController as subview Controller and selecting User Input it will display as item value at the bottom of compose sheet.
Configuration! items has title, value, and a tapHandler. So you can add extra functionality for selection from User.
ExtensionContext has list of attachment as NSExtensionItem. We’ll loop through the attachments, and look for one typed as an image. It will have the type identifier kUTTypeImage. NSItemProvider items are lazily loaded images, videos, URLs and so on. We’ll load it using “loadItemForTypeIdentifier”. This has a completion handler, where we’ll read the image from the URL, and then we’ll save it to defaults.
After pressing Post Button, It will save Image in UserDefaults with “Image” key, and contentText with “Name” key.
We have created two utility methods for saving data to user defaults and for alert message.
Till now, Apple wouldn’t accept this in their app store. We need to tell iOS when to show our share extension, and what can be selected. Otherwise when we compile we’ll get a warning.
“Warning: Embedded binary’s NSExtensionActivationRule is TRUE PREDICATE”
So for that, open the “info.plist” as source code by right clicking on it. We’re going to change the NSExtensionAttributes section. This means our extension is activated only for images, and only when it’s a single image. If you select more than one image, the extension app automatically hides from share-sheet.
You can change your display name of your app in share sheet by replacing the code in the “info.plist” of your Extension.
5. Test Your Share Extension
1. First you have to simply run your app.
2. Then run your Share Extension.
3. When suggested to choose an app to run, choose Photos.
4. Once the extension starts running, select a photo and tap on the Share button.
5. On the first run, you will need to add your extension to the share sheet.
6. Click on the More button to the right of the other share icons and turn on the switch for your extension & then select Done.
7. Now you will be able to see your extension icon in share - sheet.
8. Select an individual photo and click on share. By selecting your app, add some content and press post button.
The image will be saved to your main app. To confirm this, redirect to your app. You can check the content you entered in the textview and the image above the content.
In this article, our best iOS application developers in India, have only covered some basic UI. You can also make it more dynamic with other controls.
Hopefully, all of this will help you share data with your parent app.
Happy Coding! and feel free to share your own experience on “email@example.com”.
1. Memory Optimization :
There are wide range of devices in android, and each application perform differently on each device. So basically performance is one of the problem for Android Application Developers.
1 ) Don’t Allocate Memory to Object if it is not needed - Initializing the object at expensive places can affect the application performance a lot. It will call garbage collector frequently.
Ex. Avoid creating object inside loops and methods like onDraw().
2 ) Choose Data Structure Carefully -
Ex. We have one HashMap like
It will consider ‘1’int value which is primitive type and will allocate memory to wrap int to Integer which is also know as a Boxing technique that can be expensive in terms of performance of application.
We can use Sparse*Array which will reduce unnecessary object creation.
3 ) Working with Image Bitmaps - Bitmaps take lot of memory in our application so it is suggested that we should not load image in its full size , we should load the image in particular resolution which we are using it in our application.
Ex. Suppose we are showing the imageView of size 100 * 100 dp so we should load the image in same size, there are some common methods to perform in developer documentation of android.
4 ) Use Cache Memory - Cache allows you to use expensive object without recreating them. We can store such objects like image which we can’t afford to load again and again.We can store it in Cache memory and load them directly from Cache.
Ex. Android provides LRUCache Class , which will perform such operations for us. Class has a Storage Limit. When class exceeds its limit it will automatically removes the least used object from the Cache.
On other hand, we can also use some third party library to Cache the memory and avoid to load it again and again. Glide and Picasso are such libraries to achieve that.
5 ) Use DiffUtil in RecyclerView - DiffUtil uses Eugene W. Myer’s difference algorithm to calculate the minimal number of updates to convert one list into another. Instead of notifying all items just notify those items which are changed. For more information refer this url.
6 ) Don’ts use android:text in design layout files. - Most of the mobile developers uses android:text for layout design purpose and overwrites respected value from java classes which will writes text one time from xml layout and another from java files. So to overcome this, use tools:text instead of android:text
Android Studio provides performance tool know as a Lint which will show us our potential error in the code. We have one variable that is created in onDraw method lint that shows error for the kind of code.
2. Code Optimization :
Optimization of the code is directly related to size of our application.
1 ) Remove unused Resource - Resource like image can take much size in our apk.so we should remove unused resources from res folder.
Ex. - There are two ways to remove unused resource from apk.
CTRL + ALT + SHIFT + i - Type unused resources and Enter which will give list of resources (drawables,strings etc.) which are not used in our app currently. We can delete them.
Shrink unused resources from gradle file.
Which will remove unused resource from your release apk.
2 ) Don’t use Images for all Density - Android supports different density with different devices like ldpi,mdpi,hdpi,xxhdpi,xxhdpi. Use only those density images which you think large number of users are going to use. It is already recommended that all devices should use at least xxhdpi images.
3 ) Avoid Frame by Frame Animation - Frame by frame animation can enlarge for application, which is having multiple images for different density. Try to achieve such things with GIF images.
4 ) Reuse Images - We can use same resources like we need an image with mirror effect. So we can use same image with rotation.
5 ) Remove unused Code - Nowadays we use so many third party libraries to achieve some features easily in our app which is nothing wrong to do, but there are some unused code and classes that takes place in application.
Android provides facility of Proguard to remove such code from your application.
The 2017 Worldwide Developers Conference keynote was Apple's biggest event in years, with the company introducing both new software platforms and a range of new hardware products.
As usual, the event began with the message for developers “Keep making apps, the world is depending on you”.
And as always, the event started with a keynote during which Apple announced dates (June 5–9, 2017 in San Jose) of updates for their iOS, OS X, watchOS, and tvOS platforms.
A Giant step for iPhone, A Monumental leap for iPad
Messages App Syncs Across Multiple Devices
The first new iOS 11 feature: synchronized conversations across iCloud, iOS, and macOS. Messages are moving to iCloud.
If you erase a message on your iPhone or iPad, then it will also delete from the iPad and the Mac and vice-versa. Our conversations will be stored on iCloud, which will make them easier to retrieve your future Apple devices.
There is also an update related to Apple Pay, which will now be able to pay people. Person-to-person payments let people pay directly from Messages as an iMessage app.
It uses the TouchID fingerprint sensor. And the money which received will go into your Apple Pay Cash Card, which you can use for further Apple Pay payments, or to transfer money back into your account.
It might be helpful to make payment through application and person can directly transfer money to his friends or family members or use as general. Hence, we can enhance our application to the next level in terms of eCommerce market.
Aha, Apple has made improvements to Siri that makes assistant’s voice sound more natural when responding to users. Siri will now be able to perform translations from English to Chinese, French, German, Italian, or Spanish. Wow…
As a ios developers, we can definitely use this feature into multi-language application and give better user-interface as well as performance to our app users.
Siri is also getting smarter about suggestions. On-device, learning is synced across other Apple devices but kept completely private, readable only for you. Siri gives suggestions based on personal usage of Safari, News, Mail, Messages and more. For example, as Siri learns topics or places, a user is interested in while browsing Safari.
The camera also has lots of improvements, including improved image quality. Portrait Mode in the iPhone 7 Plus can be taken with Optical Image Stabilisation, True Tone flash and HDR.
Apple has also added a new technology called High Efficiency Image File Format (HEIF) that reduces the file size of your iPhone 7 or 7 Plus photos.
This can be helpful into the application where Image and its quality is considered as the core concept.
In iOS 11, Apple has redesigned Control Center, which is the thing that users can swipe up to access frequent and important settings or change songs when listening to music.
Drag And Drop For IPAD
Apple is specially focusing on productivity for the iPad with iOS 11.
A new drag-and-drop feature lets you quickly move info or media from one split-screen app into the other besides it. Drag and drop can also be used with apps on your dock or home screen.
Lock Screen Improvement
The Lock Screen in iOS 11 has been improved so that you can see all of your Notifications in one place.
You can see all of your Notifications, simply pull it down from the top of the screen. Then you will be able to see both your recent and missed notifications in one place.
Here, we should take care about sending an extra unnecessary notifications, as our users can’t get bored from such things. And only useful notifications should be seen to attract the user of our application.
Apple announced that the Maps app in iOS 11 will support indoor mall and airport maps. The indoor maps will allow you to see which restaurants are past security at the airport. And you can also see which stores are on what levels in the malls.
Lane Guidance in Maps now encourages you to dodge missing a turn or an exit by showing which lane you should be in when you’re navigating. You can also check the speed limit of the road.
As a mobile app developer, we should think that whether this feature can put our application into an advanced level in terms of event organization kind of feature where our users can easily find the place/stall where he needs to go.
Do Not Disturb While Driving
Apple iOS 11 has a very useful safety called Do Not Disturb while Driving. This feature helps drivers stay focused on the road by automatically silencing notifications. And you can send auto-replies to your contacts in your favorites so that they know you are driving.
App Store App Improvements: A whole new design, A whole new perspective
The App Store has been redesigned from the ground to help you discover new apps and games you can’t live without. You’ll see daily stories by experts, a dedicated Games tab, lists for all kinds of apps, and much more. It’s the biggest thing to come to the App Store since apps. And now apps that are submitted to the Apple App Store are generally reviewed within 24 hours.
Apple is building augmented reality directly into the core of iOS, giving developers the tools they need to convincingly blend digital entertainment with the real world. So with help of this new framework, we can effectively introduce augmented reality into our application.
Now, it’s like behind-the-scenes stuff for iOS. It’s getting Metal 2, of course, and a new set of machine learning APIs letting developers use Apple’s natural language comprehension and facial recognition tools.
macOS High Sierra
Your Mac. Elevated
macOS High Sierra introduces new core technologies that improve the most important functions of your Mac. From re-architecting, it shows how it stores your data & how you watch videos to unleash the full power of the graphics processors.
Apple File System
To your Mac, everything you care about is data. And a file system is what organizes all that data into files and folders you can access with a click. Apple’s current file system was designed in the early days of Mac, and it has performed beautifully ever since. But today’s flash‑based Mac opens up new possibilities for innovation, so it’s time to lay a new foundation. With macOS High Sierra, Apple is introducing the Apple File System to Mac, with an advanced architecture that brings a new level of security and responsiveness.
Below are some bullet points about updates in macOS High Sierra:
More intuitive, More intelligent, More you
Apple announced a new version of watchOS. One of the most noticeable changes in watchOS 4 is the option of using a Siri watch face. This automatically displays contextual information on the Apple Watch, such as approaching appointments, and traffic reports if the wearer is going to work.
New fitness feature includes in controls, more prompts to set goals, and two-way workout data exchange with certain gym equipment. The Apple Watch will also be able to better connect with other hardware gadgets, such as continuous glucose monitors and smart tennis rackets, via NFC. This can be a useful feature where our application also interact with Watch OS.
watchOS 4 also includes a new Music app meant to improve the AirPods experience. Multiple playlists can now be synced including Apple Music-recommended playlists.
The Dock on watchOS 4 has a new look with a vertically scrolling interface with can lead to the UI Interface of the watch application. watchOS 4 can also automatically start when workouts are started, and music playback controls are integrated with the Workout app.
Control Center gains a new flashlight function using the display which also works during outdoor, night workouts as a safety feature.
In WWDC 2017, one thing to say from apple about tvOS, The Apple TV is getting a big new content, as Amazon Prime Video is coming to Apple TV and Apple’s new TV app.
New Macs and the iMac Pro
Now faster across the line
Apple also upgraded its MacBook and MacBook Pro lineup with faster processors and SSDs. It also refreshed the MacBooks.
Apple’s 13-inch MacBook Pro without the Touch Bar on top now comes with Intel core i5 processor clocked at 2.3GHz, 128GB Storage and 8GB RAM. This also has two Thunderbolts 3.0 ports.
iMac Pro: The most powerful Mac ever
The all-new iMac Pro, with its gorgeous 27-inch Retina 5K display, up to 18-core Xeon processors and up to 22 Teraflops of graphics computation, is the most powerful Mac ever made. iMac Pro packs incredible performance for advanced graphics editing, virtual reality content creation and real-time 3D rendering.
Any you can do, you can do better
The new version of the iPad Pro has a 10.5-inch display, 20 percent larger than the previous 9.7-inch model. Apple said that It features a better display with richer color and a new feature called ProMotion, which updates its content up to 120 times per second making it feel smoother and more responsive.
HomePod: Apple’s new Siri speaker
The HomePod has seven tweeters and four-inch woofer; it has an A8 chip living inside it. That’s a feature Sonos has too, letting the speakers adjust their output to, say, push the vocals down the centre of the room while bouncing the bass off the wall.
A feature will respond to “Hey, Siri,” play from your Apple Music account, and answer questions about the music it’s playing. It will also handle other Siri queries, such as weather, news, messages, podcasts, stocks, controlling smart home devices via HomeKit, etc.
Above are the announced points of Apple during WWDC 2017. Though we haven’t had a chance to look through everything yet, feel free to post any missing points or share your thoughts about these new features in iOS app development.

Bluetooth Low Energy is a wireless personal area network technology designed by the bluetooth Special Interest Group (SIG).
Bluetooth low energy (formerly known as Bluetooth Smart) is a universal low-power wireless standard that makes it easy to connect any product to a smartphone or tablet.
The most common use case of bluetooth low energy is transferring small amount of data between nearby device.
Support for bluetooth low energy is available on most major platforms as of the versions listed below
BLE is used for making application type of connected watches, tracking tags, sports and fitness sensors, healthcare sensors and remote controls. It is also seen in Smart Home applications such as connected door locks and lightings.
Advantages of BLE are :
The device called “Beacon” works on a BLE which is charged by Battery or USB transmits the signal to our device.
It is important to understand that BLE and Bluetooth both are completely different technologies. Bluetooth transmits more data with more range, whereas on other hand BLE share small amount of data with shorter range.
Each BLE Beacon consists a Unique identifier known as a UUID.
Beacon also give data like distance from beacon, major and minor proximities of beacon.
As compared to GPS which is also used to get user’s location where he/she exactly are located, GPS consume more power and might not work in some indoor location in other hand. Beacon are better option to get Proximity (Immediate,Near,Far) location and distance in indoor locations too.
Now Beacons can be used in many ways. Retailers have already started using it in such a way like,
As a Mobile Application Developer (Android Developer) we should look into some practical part too. So, basically there are four things which we need to understand.
1. Beacon Region- Regions are specific area defined by the beacon with its UUID.
2. Beacon Monitoring- It is a technique to find a beacon when user enters in the Region of the beacon or exits from the region.
3. Beacon Ranging- It is a technique to get list of beacons which are in the region and can get beacons proximity, distance, UUID, Major and Minor.
4. Beacon Transmitting- It is a technique to use Mobile Device as a Beacon device, a device which is compatible to transmit the beacon.
There are so many SDK’s and Libraries available in the market to achieve this thing simply and from that some are paid and some are free. Choose the best library available in the market as per your requirement.
9series, a top mobile app development company, has widely worked across both iOS and Android platforms, making splendid apps adored by all smartphone users everywhere throughout the world. Being an accomplished mobile app development specialist, one can state that their mobile apps gather best response among clients and yield greatest engagement.
An app extension allows you to fabricate custom functionality and content ahead your iOS app and make it accessible to users while they’re interacting with other apps or the system.
App extensions give users access to your apple app development functionality and content throughout iOS and OS X. For example, your app can now appear as a widget on current screen, offer photo filters within the Photos app, add new buttons in the Action sheet, or display a new system-wide custom keyboard. Use extensions to place the power of your app wherever your users require it most.
1. Action Extension
Action extensions permit users to transform content arising in a host app without leaving the app. You can, for example, edit images, change the text format and change the content itself, etc. At WWDC 2014, Apple revealed a demo of an Action extension that translated the text of a web page to another language without leaving Safari.
When you build a new action extension, Xcode creates a template which when used without modifying its configurations, will arise in every single action sheet by default. It won’t show any checking of the content types to decide whether or not it’s suitable for the host app.
You can make two types of action extensions: one with a user interface and one without a user interface. If you prefer the latter one, it will be restricted to Safari, but if you provide a user interface, then the extension can be made available to other apps that show that the extension supports the type of content to be transformed.
2. Audio Unit Extension
An Audio Unit app extension provides users a suitable way to build or modify audio in any iOS or macOS app that uses sound, including music production apps such as Logic Pro X or GarageBand.
The Audio Units extension framework is basically an enhanced approach to use audio apps like effects and virtual instruments within audio host apps, like Apple’s own GarageBand or other audio editing and merging apps. With the help of Audio Units, Apple let's audio plug-ins show up as UI within another app, enhancing the workflow and making the experience much like what experts are used to on the Mac in apps like Logic Pro.
3. Broadcast Upload Extension & Broadcast UI Extension
ReplayKit was introduced in iOS 9 as an approach to give users a chance to record themselves using an app or game, then share it with friends. iOS 10 takes the entire process a step further by presenting live broadcasting of ReplayKit streams, and does so by developing on existing live streaming services: users install apps that support live streaming and ReplayKit lets you clasp into them.
So, let's say you want to stream somebody's game to a service like Twitch: you begin by creating a RPBroadcastActivityViewController to let the user select which streaming service they want to use. They will revert back a RPBroadcastController that can start, pause, and stop live broadcasts, and furthermore let you know whether broadcasting is currently happening through its isBroadcasting or not.
4. Call Directory Extension
Apps can build a Call Directory Extension to recognize and hinder incoming callers by their phone number.
Both recognizing and hindering of incoming calls is set up in the implementation of the beginRequest(with:) method of the CXCallDirectoryProvider subclass of Call Extension. This method is called only when the system launches the app extension.
When a phone accepts an incoming call, the system first advises the user’s contacts to locate a matching phone number. If no match is found, the system then advises your app’s Call Directory extension to locate a matching entry to recognize the phone number. This is beneficial for applications that keep up a contact list for a user that is detached from the system contacts, such as a social network, or for classifying incoming calls that may be initiated from inside the app, such as for customer service support or a delivery notification.
To provide recognizing information about incoming callers, you use the addIdentificationEntry(withNextSequentialPhoneNumber:label:) method in the implementation of beginRequest(with:).
5. Content Blocker Extension
In iOS, a Content Blocker extension personalizes the way Safari manages your content. The extension adapts your content by blocking loads, hiding elements and dismantle cookies from Safari requests.
Using a Content Blocker extension, you grant Safari with content-blocking rules that define how Safari treats content such as scripts, images, and pop-up windows. Your rules can cover Safari-downloaded content or keep Safari from requesting particular content from the server. By reducing the number of content Safari requests, your extension can decrease the amount of time required to load pages. When you obstruct content from loading, you decrease Safari’s memory usage and enhance Safari’s performance.
In addition to obstructing unwanted content, a Content Blocker extension protects privacy.
6. Custom Keyboard Extension
A keyboard extension switches the standard keyboard with a custom keyboard. Custom keyboards are enabled in the Settings app, under General > Keyboards. Once enabled, the keyboard is accessible amid text entry within any app, aside from when editing secure text fields and phone number fields. People can enable multiple custom keyboards, and shift between them at any time.
7. Document Provider Extension
The Document Provider extension permits an app to share its documents with other apps on a user’s device in a secure and timely manner. If you have ever used the Document Picker, you might have appreciated all the apps in the Locations section.
The Document Provider extension performs as the link between the files that your app handles and other apps on the user's devices. It lets different apps import or open the files, downloading and uploading them from your server as required. Apps can also export or move their documents into your extension’s shared repository.
The Document Provider extension comprises of two separate parts: the Document Picker View Controller extension and the File Provider extension.
8. iMessages Extension
These app extensions permit developers to add new functionality directly to the Messages app in iOS 10. Users will soon be able to play games, exchange money, send videos, or make restaurant reservations all within the context of their existing iMessage conversations. Mobile App Developers can now build their own different types of apps, that vary from sticker packs to fully interactive interfaces which generates inline iMessage content.
iMessage apps work similarly as extensions. If you already have an app and need to provide iMessage functionality, you won’t require making a whole new app. You can just plug in the iMessage functionality and submit to the App Store. There’s likewise going to be a mini version of the App Store, particularly for iMessage apps, incorporated right into the Messages app. The user will be able to browse all apps compatible with iMessage and install them – right at the spot.
These app extensions are incredible features in ios app development that apps should take advantage of. In this article we, as a mobile app developers, have emphasized some of the key extensions in app. And for further more app extensions, let’s get in touch with the upcoming article.

We, 9series has started looking forward for the latest version of IDE for iOS App Development i.e. Xcode 8. At WWDC 2016, Apple announced Xcode 8, the latest version of its IDE for iOS, macOS, tvOS, and watchOS. With every major release, the company enhances its developer tools and adds a number of compelling new features. Xcode 8 is released with major improvements like Swift 3, address and thread sanitizer, a new editor extension architecture, and more.
9series strongly believe that by using these latest features, development can be done faster and can be pushed ahead with the next strides.
Before downloading the latest version of Xcode i.e. Xcode 8, let’s check with its compatibility.
Xcode 8 requires a Mac running macOS El Capitan version 10.11.4 or later. It includes SDKs for iOS 10.0, watchOS 3.0, macOS Sierra version 10.12, and tvOS 10.0.
Swift Migration Tool:
Projects that are built with Xcode 8 uses Swift 3 by default. Fortunately, Xcode 8 includes a build setting that provides developers the ability to stick with Swift 2, Swift 2.3 to be precise. A Swift Migrator is implemented to help upgrade your Swift code to the latest Swift 3 language specification and SDK requirements.
Source Editor Extensions:
Xcode 8 adds support for Xcode source editor extensions. Application extensions provide additional commands in the Xcode Editor menu. These extensions can manipulate and navigate both text and selections. To perform them, use the new Xcode Source Editor Extension target template in the macOS Application Extensions section when building a new project. Apple emphasizes that extensions are currently focused on manipulating and navigating the contents of the source editor hence source editor extensions. It runs in a separate process. It means a crashing extension doesn't cause Xcode to quit unexpectedly. Another great benefit is that you can create your own extension and distribute using your developer account.
Signing Made Easy and Powerful:
The new automatically managed code signing generates all the assets you need to properly sign, provision, and run your apps on a connected Apple device. Simply choose your team and Xcode will do the rest. You also have the option of hand-picking your provisioning profiles and setting up the signing process for each build configuration.
Debugging:Xcode 8 introduces runtime issues in addition to build time issues. If you run Auto Layout issues at runtime, Xcode shows you the issue as a runtime issue in the Issues Navigator on the left. This is very esteemed addition.
Apart from above, there are few more additions to Xcode mentioned below:
Though no softwares can be complete or in finished version. There may be some issues, pros, cons and enhancements, which Xcode can also have. There are many improvements in Xcode 8 and we can definitely go for it and use it.
In this article, we, 9series, have only covered a subset of what is new in Xcode 8. Developers need to spend more time to review these points in detail and of course, rest of them needs to have more experience of this latest tool.
Feel free to share your own experience of Xcode 8 with us.
