Run swift script from Xcode iOS project as build phase

Question

Here is a simple swift script:

#!/usr/bin/env xcrun swift

import Foundation

let task = NSTask()
task.launchPath = \"/bin/echo\"
task.arguments = [\"farg1\", \"         


        

Answer 1

If you unset the SDKROOT environment variable before calling the swift script, it will then use the OS X sdk.

Answer 2

When building for iOS the implicit SDK for xcrun is the iOS SDK, so you have the change it to the Mac OS X SDK with a command line parameter. Change the first line in your script to:

#!/usr/bin/env xcrun --sdk macosx swift

Answer 3

+1 for @Mats's answer.

For anyone who get an error like *** is only available on OS X 10.11 or newer.

You can:

#!/usr/bin/env xcrun --sdk macosx swift -target x86_64-macosx10.11

UPDATE 1:

If you don't get ready for Swift 3, but you are using Xcode 8, you can also control toolchain version:

xcrun --toolchain com.apple.dt.toolchain.Swift_2_3 -f swift

So:

#!/usr/bin/env xcrun --toolchain com.apple.dt.toolchain.Swift_2_3 --sdk macosx swift -target x86_64-macosx10.11
