# endTurn(withNextParticipants:turnTimeout:match:completionHandler:) Passes the turn from the current participant to the next participant. ``` func endTurn(withNextParticipants nextParticipants: [GKTurnBasedParticipant], turnTimeout timeout: TimeInterval, match matchData: Data, completionHandler: (@Sendable ((any Error)?) -> Void)? = nil) ``` ## Parameters `nextParticipants` Match participants in the order you want Game Center to pass the turn. Game Center passes the turn to the next participant in the array when communication fails or a participant doesn’t finish their turn within the time limit. Elements in this array must be in the [`participants`](/documentation/GameKit/GKTurnBasedMatch/participants) property. `timeout` The length of time a participant has to complete their turn before Game Center passes the turn to the next participant. The maximum value is 90 days. `matchData` Your game-specific data representing the match state. For example, include information needed for the next participant to take their turn in this object. Don’t pass `nil` as this parameter. `completionHandler` The block that GameKit calls when it completes the request. The block receives the following parameter: - *error*: Describes an error if it occurs, or `nil` if the operation completes. ## Discussion Invoke this method only when the local player is the current participant. To receive turn-based events that this method generates, register a listener that conforms to the [`GKTurnBasedEventListener`](/documentation/GameKit/GKTurnBasedEventListener) protocol with the local player.
