Support for XCTest skipping

[ARSteve]

There is support now for skipping tests in XCTest ( https://developer.apple.com/documentation/xctest/methods_for_skipping_tests?language=objc )

Would be great to have support for processing this output in trainer.

Yeah it would be great to have it forward along skipped tests into the JUnit output using what support that report format has.

Does interest exist to support this? I have not attempted to understand how to contribute to trainer, hoping someone more in the loop could pick up this issue and attempt to implement support for it.
