[swift-corelibs-dev] [XCTest] Cannot build using XCode

Wow, the swift build is a success. Though there are a few warnings at the
end. I guess the issue was with cached values in the build directory.

But, in the next step to build xctest using "/utils/build-script --preset
corelibs-xctest", the build fails. The build error log is given below.

------------------------

CompileSwift normal x86_64
