There is a significant difference between using Xcode as a product that builds your project and using frameworks and headers contained inside the Xcode.app bundle to link with your project.
With ‘not supported’ I mean that, unless stated otherwise, frameworks contained inside the Xcode.app bundle are considered internal implementation details and we reserve the right to completely change them between Xcode versions (the ABI may change or the framework eliminated entirely, etc.); even though such changes may not have any observable changes for _using_ Xcode.app.
