[swift-users] How to get Swift 2.3 in command line?

[Sikhapol Saijit]

If you already have two versions of Xcode installed in the /Application then I think using xcode-select tool would be easier.

type sudo xcode-select -s /Application/Xcode.app will get you Swift 2.3 and all the environment of Xcode 7

sudo xcode-select -s /Application/Xcode-Beta.app will quickly switch everything to Xcode 8
