Documenting Swift protocol

In Swift, I can write documentation at a protocol level now. There is a kick-ass feature added recently to Xcode 8 (beta 4). If I add documentation of function at the protocol level, it's available at the level of implementation.

look, I wrote documentation to and I can read it in MyTask implementation. So great!

I'm so excited about this little feature being added. Some time ago I faced this documenting problem and I just hoped it would be added at some point, and apparently it is!
