How do you get it? I downloaded the new beta and the beta Xcode but all I have is swift 4.1.2 when I check with Terminal, swift -v

I tried some of the ML examples from the WWDC videos and one of the last example didn’t work. I noticed in the video they were using v4.2

Thanks

Update:

It does come with Xcode beta 10L176w after all. I selected it in Xcode beta > Preferences > Locations > Command Line Tools > Xcode 10.0 (10L176w) :wink: Now Terminal > swift-v shows 4.2 and xxxx.swift files run with ML code!!! (from the WWDC video)

Hi shogunkaramazov

It wasn’t on by default when I installed Xcode but found that if I went to Preferences : Locations and selected it as the CommandLine Tools version it was available.

Thanks.
