Use Swift 2.2 in Xcode 8?
SwiftSwift2Xcode8Swift Problem Overview
Is it possible to use Swift 2.2 in Xcode 8?
From Xcode 8 release notes:
> "Xcode 8 supports switching toolchains, such as those from swift.org, > without relaunching Xcode. (23135507)"
I have been trying to find swift 2.2 toolchain on swift.org website but couldn't. Have any one success in configuring Xcode 8 to work with swift 2.2
Swift Solutions
Solution 1 - Swift
If you want to continue to use Swift 2 in Xcode 8, then use Swift 2.3 by enabling the Use Legacy Swift Language Version build setting (SWIFT_VERSION = 2.3).
Solution 2 - Swift
Using Swift 2.3 in Xcode 8 by That Thing in Swift provides a good introduction to using Swift 2.3 in Xcode 8.
The following is quoted from the article:
> There’s a single build setting that will let you continue building > your Swift projects with a Swift version that’s mostly similar in > syntax to your existing projects from Xcode 7: Use Legacy Swift > Language Version > > Just drop into your project’s build settings and search for legacy > swift to find the correct build setting, then switch the setting to > YES to opt-in to Swift 2.3 rather than Swift 3 in Xcode 8.
Solution 3 - Swift
It is not possible to use Swift2.2 in XCode8, and it is also not possible to use Swift2.3 or Swift3 in XCode3.
The best solution i found is to create a single project file that will compile for both iOS 9 (Xcode 7) and iOS 10 (Xcode 8), and that will support Swift2.2 and Swift2.3 (very similar).
Solution 4 - Swift
As one of possible solutions to this problem I could suggest to install two versions of Xcode (7.3.1 and 8, for example) side by side.
To accomplish this you should:
- Download suitable dmg file from Downloads for Apple Developers. Use search to find Xcode.
- Double click this file to see familiar “Drag to install Xcode in your Applications folder” window. But drag this somewhere else for a moment. Desktop would be good. Rename it to Xcode \number of version\ (like Xcode 7.3.1) and then drag it to Applications folder.
That's it.
Solution 5 - Swift
It is not possible to use Swift2.2 in XCode8 by setting Use Legacy Swift Language Version to Yes in Build Settings.
