How do you implement real-time multiplayer in iOS games using GameKit?

Problem Faced:
Developers struggle with synchronizing real-time multiplayer game states across devices and handling connection drops.

Solution:
Use GameKit's GKMatch API for real-time player connections.
Synchronize game state using match.sendData(toAllPlayers:with:).
Implement retry mechanisms for dropped connections.
Use delta compression to send only changes in game state instead of full updates.

swift

do {
    let data = try JSONEncoder().encode(gameState)
    try match.sendData(toAllPlayers: data, with: .reliable)
} catch {
    print("Failed to send data: \(error)")
}
