Carthage: Building dependencies with Swift 2.3 rather than Swift 3 when using Xcode 8 Beta

[iliaskarim]

How do I build dependencies with Swift 2.3 rather than Swift 3 when using Xcode 8 Beta?

I wasn't able to find a solution by searching so I thought I'd open an issue. Thanks in advance for any assistance!

• carthage version: 0.16.2
• xcodebuild -version: Xcode 8.0 (Build version 8S128d)
• Are you using --no-build? no
• Are you using --no-use-binaries? no
• Are you using --use-submodules? no

I haven't tested, but it looks like there's a solution in #1350

[iliaskarim]

cheers @dcaunt, appreciate the link

the following command indeed worked, it used Swift 2.3 to build my Carthage dependencies:
TOOLCHAINS=com.apple.dt.toolchain.Swift_2_3 carthage bootstrap --platform ios

sadly Alamofire still doesn't build because of changes within the iOS SDK 😩

does it make sense to try and build dependencies with the iOS 9.3 SDK? If so, anyone know how?

[AndrewSB]

@ILI4S that sounds like an Alamofire issue - if Alamofire pushes a swift-2.3 branch (2.2 -> 2.3 are minimal changes), you'd be able to build Alamofire

[AndrewSB]

@ILI4S try using this fork of Alamofire instead? https://github.com/KingOfBrian/Alamofire/tree/feature/Swift2.3

[mdiep]

You should also be able to specify the toolchain with Carthage's --toolchain argument.

Either way, Carthage is doing the right thing here. Dependencies will need to be updated to work with Swift 2.3 before you can move to Xcode 8.

[mythical-programmer]

When I am installing via Pods, I am using
pod 'Alamofire', '~> 3.4'
But the installation is completing with Alamofire 3.5.1 !?

How to approach further ?

[AndrewSB]

@codinggenie that looks like a question for the Cocoapods repo

[loretoparisi]

I have tried the solution above

 TOOLCHAINS=com.apple.dt.toolchain.Swift_2_3 
carthage build
carthage update

where my Cartfile is

github "Alamofire/Alamofire" >= 3.1.0

but after I build, Xcode still complains I cannot import a module compiled for swift 3.0.1 in a module compiled for swift 2.3.

[mediumbear]

Digging around the build log, I saw an export. To build with Swift 2.3, first
export TOOLCHAINS=com.apple.dt.toolchain.Swift_2_3
and the build will work (using XCode 8.2.1)

[seclorum]

Also works:

$ TOOLCHAINS=com.apple.dt.toolchain.Swift_2_3 carthage update
