Hi @Charles66666666 the title of this issue seems to indicate you're running xcbuild in a linux environment. I would suggest you take a look at #37
If you are indicating that xcodebuild performs the build but xcbuild does not, I would appreciate it if you could tell me the version of Xcode.app and your macOS verison?
