I've recently pulled the source code to build swift and downloaded all the related submodules, I want to be able to test ExpressibleByStringInterpolation new implementation, but I am unable to build anything, I always end up getting this error:
clang: error: invalid version number in '-mmacosx-version-min=10.10' --- bootstrap: error: build failed with exit status 1 ./utils/build-script: fatal error: command terminated with a non-zero exit status 1, aborting ./utils/build-script: fatal error: command terminated with a non-zero exit status 1, aborting
All I'm doing it building using ./utils/build-toolchain macOS within the Swift folder. I have Xcode 10.0 installed on my system.
What's going on here?
Thank you for your help.
