Build failing with error: Swift does not support the SDK 'MacOSX10.12.sdk'

Development Compiler

Hello,

I guess this has something to do with the recent updates to build
requirements.

I have downloaded Xcode 9 beta, and used xcode-select to use that version
from command line. What else do I need to do to make Swift build again on
Sierra with Xcode 9 beta?

Best regards

Hi Pavol,

Make sure you are running Xcode 9 beta 1 on macOS 10.12.4+, also delete the build directory from previous Xcode before building with new Xcode.

Thanks,

Oh, maybe I should do a clean build… :-)
