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

[Keith Smiley]

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
