Rewarding players with achievements

## Return Value

## Discussion

Discussion Before creating an achievement, use the loadAchievements(completionHandler:) method to load the achievements that are in progress. If the achievement you want to report progress on isn’t in the array that GameKit passes to the handler, use this method to initialize the achievement, but only when reporting progress for a participant at the end of a turn-based match. Otherwise, use the init(identifier:) method to initialize the achievement.
