Apple Insider:
As detailed by Apple at a session during its Worldwide Developers Conference last week, games will have access to new tools for inviting friends to multiplayer games via the Messages app.
Apple told developers that those already using existing Game Center invitation APIs won’t need to make any code changes for iOS 10. Messages-based invites will automatically replace the old method of inviting friends to play, and anyone can be invited via the Messages app and iCloud.
This is an interesting left turn for Game Center and the Messages app. Messages looks to be a delivery mechanism for a richer set of iOS-specific messages. And given that Messages also runs on the Mac, those messages will be available cross-platform. I look forward to seeing how this evolves over time.
When word spread that you’d be able to delete certain apps from iOS 10, I was bummed that Game Center wasn’t on the list. No one said they were getting rid of it. This is awesome! For me, Game Center is nothing but a barrier between me and the game I want to play.
They need to tap into Twitter contacts. I know Twitter is the firewall here. But I have so many friends on Twitter and nowhere else like Contacts or Facebook.
