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

[Zhao Xin]

Thank you Keith. You helped me a lot. I finally got it work.

As realm use "xcrun swift" to get swift version. I did that by 'export
TOOLCHAINS=com.apple.dt.toolchain.Swift_2_3'.

I also think the document in https://swift.org/download/#using-downloads should
change

$ export
> PATH=/Library/Developer/Toolchains/swift-latest.xctoolchain/usr/bin:"${PATH}"


to export  TOOLCHAINS as well.
