There’s nothing about a nil return, so I don’t understand why they’re bridged into Swift '[…]!’ types, since *surely* they return an empty array if there aren’t any devices or formats, and there’s no error return. Maybe just a missing nullability annotation.

Thanks (to both of you). Quincey's comments reassure me that I was indeed correct in thinking things should work a certain way, and Roland's explain why I'm seeing what I'm seeing.
And by "Swift sucking," I guess I meant Xcode, in that it still has numerous issues with code completion.
