Hoping that someone could confirm or disprove the fact that achievements do not appear to show when they are achieved. When launched on an iOS 6 device, the achievement appears, but when launched on iOS 7 it does not appear.
Use to showsCompletionBannerset the value YES. https://developer.apple.com/library/ios/documentation/GameKit/Reference/GKAchievement_Ref/Reference/Reference.html#//apple_ref/occ/instp/GKAchievement/showsCompletionBanner
showsCompletionBanner
YES
Atm I assume this is a bug in iOS7 and it will be fixed (who knows), so I don’t touch any code.
