Some questions:
1) Is "xcodebuild -sdk / -version SDKVersion" returning the proper
version? I bet not because you called / an invalid argument.

2) Would it make sense to perform some pre-checks before applying my
"hack" in case sdk is a path? For example if it starts with the output
of "xcode-select --print-path"

Thanks,
