• Leaderboards：Easily get one or more leaderboards by specifying the leaderboard ranking method in App Store Connect.
• Achievement Logging：If the game has defined milestones, progress can be saved using Game Center.
• Challenges：Game Center provides mechanisms that enable player-to-player challenges.
