Type Method


Reports a list of achievements and limits the challenges those achievements may complete.


class func report(_ achievements: [GKAchievement], withEligibleChallenges challenges: [GKChallenge], withCompletionHandler completionHandler: ((Error?) -> Void)? = nil)



An array of GKAchievement objects that represents all achievements that are being reported.


An array of GKChallenge objects that represents the limited challenges that are associated with the reported achievements. If an error occurred, this parameter may be non-nil, in which case the array holds whatever challenge information Game Kit was able to fetch.


A block to be called when the download is completed.

The block receives the following parameter:


If an error occurred, this object describes the error. If the operation completed successfully, this value is nil.


When this method is called, it creates a new background task to handle the request. The method then returns control to your game. Later, when the task is complete, Game Kit calls your completion handler. The completion handler is always called on the main thread.
