Game center have several new features that will help you with your games. Some of them have been listed as follows:
- Increased limit of leaderboards per application: Now you can have up to 100 leaderboards in your game.
- New feature—exchanges: This allows your turn-based player to initialize actions even if it is not their turn. Previously, you had to wait for your turn to even chat, and now you can do that on other players' turns if the game supports that.
- Improved features to prevent cheating: Cheating, obviously, is never good, especially if your game is competitive and has leaderboards. We all know how such games are infested with hackers, and these new features will certainly help with that.
