What's new in Xcode 8.3?

Xcode 8.3

Swift 2.3 Deprecation

  • Xcode 8.3 beta 2 no longer supports Swift 2.3. Please migrate your projects containing Swift 2.3 code to Swift 3 syntax by opening the project and choosing Edit > Convert > To Current Swift Syntax.

Other Deprecations and Removal Notices

  • The Automation instrument has been removed from Instruments. Use Xcode’s UI Testing in its place.

Organizer

  • The Xcode Organizer now supports exporting tvOS apps for Enterprise distribution.

Testing

  • Added the XCUISiriService class to XCTest for writing tests which activate Siri with a voice recognition string, and queries for elements in the Siri UI. Use the class to write UI tests for Intents and Intents UI extensions.

Swift Compiler

  • The Swift compiler can now automatically precompile Objective-C bridging headers, which can speed up Debug configuration builds (or other non-WMO builds) of mixed-source projects with large bridging headers. This feature is still experimental, and is disabled by default but can be enabled with the “Precompile Bridging Header” (SWIFT_PRECOMPILE_BRIDGING_HEADER) build configuration setting within Xcode.

Provisioning

  • Changed the user interface for managing signing certificates and provisioning profiles. Certificates are managed from the Accounts preferences pane by selecting a team and clicking Manage Certificates. Automatically managing signing is recommended, however if your app requires manually signing provisioning profiles are managed in the General tab of the project editor. Use the Provisioning Profile dropdown to import or download profiles. In addition it displays profiles that match the current signing configuration of the target.

Simulator

  • You can invoke Siri using Hardware > Siri after enabling Siri in the Settings app on Simulator.

Others

  • Xcode 8.3 includes Swift 3.1 which is intended to be source compatible with Swift 3.0.
  • Constrained extensions allow same-type constraints between generic parameters and concrete types. For example, the following code defines an extension on Array with Int elements:
  • The Swift compiler now raises an error for modifications of a let property or variable of protocol type after initialization. For example, the following code that compiled in previous versions will now raise an error:

    Code that successfully compiled in previous releases may fail after upgrading.

Interface Builder

  • NSTextField objects created in Interface Builder now have allowsCharacterPickerTouchBarItem turned off by default.

Currently latest beta version is Xcode 8.3 Beta 3. I will update this blog as per versions of Beta.

Steps to use Legacy Swift in Xcode 8

Xcode Swift iOS10

Xcode 8.0 is released with Swift 3 and Swift 2.3 compatibility.


If you already having a project with Swift 2.2 language support with Xcode 7.3.1 and you open the project in Xcode 8.0 then, you will be prompted for the migration assistant to do a migration pass. The assistant can also be invoked manually from the menu Edit -> Convert -> To Current Swift Syntax…

  • Use Swift 2.3 Modifies your project to enable the Use Legacy Swift build setting and provides source changes to be able to build against the new SDKs.
  • Use Swift 3 This is recommended. You will get source changes to be able to build your project using Swift 3 and take advantage of all the new features in Xcode 8.0.

If you want to work with new project and you want to work with Legacy code (Swift 2.3) or 3.0 then you can do settings from build settings as follows :

Build Settings - Swift Legacy Code
Build Settings – Swift Legacy Code

Default Setting is No (Swift 3). But if you want to do legacy code (Swift 2.3) then you have to select Yes (Swift 2.3).
Make sure you do this setting by starting of new project because many methods will change.
For Example :
Swift 3 Code
[code language=”obj-c”]
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
// Override point for customization after application launch.
return true
}
[/code]
Swift 2.3 Code
[code language=”obj-c”]
func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject : AnyObject]?) -> Bool {
return true
}
[/code]
As per my opinion Swift 3 is recommended.

We can get the Facebook post via graph API : /me/posts for that we have to add user_posts permission with login.

Get Reactions from one of the Post

We can get the Facebook post reactions via graph API : /{post-id}/reactions. We have to pass parameters like fields and summary as described in getReactions function.

Use of Operator Overloading with Swift

apple_swift_logo

I was just going through the Swift document and I found that Swift allow to overload the operator just like as C++ Language. Objective-C doesn’t allow to overload the operator.
As swift document we can also say “Operator Functions”.

Let’s Overload ^ (XOR Operator) to make Power of the value

Function Prototype :
Declare function prototype with left hand side value and right and side value.

Operations in the function :
To make the power of the value we have to apply following operations

Let’s try to use with the operator :
