Ah, and one more comment: even after installing Xcode 7.3.1 and its Tools, my attempt to build Swift 2,2,1 failed. I had renamed Xcode 7.3.1, then used `xcode-select --switch` to switch to its correct path. However, I noticed in the build log that the new path wasn't being used.
Apparently, the script doesn't use `xcrun` to select the correct version of the Tools - it has the path hard-coded to Xcode.app/... As a result, to make it work, I had to rename my current Xcode to somethig else, then rename my copy of Xcode 7.3.1 back to Xcode.app. On Sun, Nov 19, 2017 at 6:54 PM, leanne via swift-dev <swift-dev@swift.org> wrote: > Yep, that worked, Slava.
