We don't know exactly what it is because the Xcode format is not
documented publicly.  I suspect Xcode uses some form of serialization
tool to store its internal data structures to the .pbxproj file, and
these are the ids it generates.

Effectively it is a UUID for our purposes.  The ordering Gregor
proposes is to match what Xcode writes when it generates the .pbxproj
file, and we can't choose that.
