How to get Swift 2.3 in command line?

Zhao_Xin · 2016-08-11T04:44:07.000Z

I try to change command line tool from Xcode 8.0(8S193k) to Xcode
7.3.1(7D1014), who lead me to swift 3.0 or swift 2.2. I need Swift 2.3 to
build Realm Cocoa from its source.

Any idea?

There are two toolchains under Xcode-beta.app/Contents/
Developer/Toolchains/.

Swift_2.3.xctoolchain/
XcodeDefault.xctoolchain/

So in a terminal. input

export PATH=/Applications/Xcode-beta.app/Contents/Developer/
Toolchains/Swift_2.3.xctoolchain/usr/bin:"${PATH}"

After I did that, when I input swift, it would be 2.3, but when I type
xcrun swift, it was still 3.0 or 2.2.

Any idea?

You can accomplish this with the `--toolchain` `xcrun` argument. It took a few
tries but it seems as though this command works:

xcrun --toolchain "com.apple.dt.toolchain.Swift_2_3" swiftc -v

I got this identifier from:

/Applications/Xcode-beta.app/Contents/Developer/Toolchains/Swift_2.3.xctoolchain/ToolchainInfo.plist

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 Swift.org - Download Swift should
change

$ export

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

to export TOOLCHAINS as well.

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

Thanks, Sam. However, as in Xcode-Beta.app, there are two version of Swift,
3.0 and 2.3, and 3.0 is chosen if I do your method.
