GameKit Multiplayer

GameKit is Apple's native framework for adding multiplayer functionality to games and apps on iOS, macOS, and visionOS. It provides matchmaking (finding other players), turn-based and real-time gameplay, peer-to-peer connectivity, leaderboards, and achievements. GameKit abstracts away the complexity of network communication—you focus on game logic, not sockets. GameKit is primarily peer-to-peer, meaning players' devices communicate directly. It handles Bluetooth, WiFi, and cellular connectivity automatically. For turn-based games (chess, strategy), it queues moves between players over Apple's servers. For real-time games, peers synchronize state continuously.
