xCode 11/12 support?

[GrabbenD]

Our xcworkspace works with xCode 11 and 12 on macOS but we unfortunately are not able to run it with this project on headless Linux. We're encountering various warnings and errors on start such as:

Then it fails to creating product structure:

This is pretty much only an xcbuild specific issue - and unfortunately, upstream development of xcbuild seems to have stopped, so this would require someone to pick up and continue that development.

For building source with other build systems than xcbuild, the latest version of xcode-cross should work fairly ok with Xcode 11 and 12 bundles though, I think.
