Agreed – I think for now I just have to proceed as though the scoped IDs weren't announced yet.

Obviously relevant at the moment.I'm attempting to finalize my first Game Center game after years of watching the APIs, and I'm not succeeding in finding out how to use the new scoped IDs while avoiding playerID entirely. For example, I can't see there's even one available pattern for obtaining scoped identifiers for the local player's Game Center friends in order to invite them to a match. Meanwhile, the existing methods for this pattern – obtaining and using a playerID to form a match request – appear to have been deprecated as well.I get the feeling WWDC 2020 is going to bring a wave of clarity along with some of this seemingly unreplaced functionality, and that the video presentation about the scoped identifiers are more of a sneak peek than a true call for conversion to what will replace it. But that's entirely inference, and that clarity seems merited at the mention of these new APIs and deprecations.
