Problems with GKLocalPlayer and saveGameData

Question

I want to save game data with GKLocalPlayer and saveGameData method.

[localPlayer saveGameData:playerData withName:@"SolarFlares" completionHandler:^(GKSavedGame *savedGame, NSError *error) {
    if (savedGame != nil) {
        NSLog(@"Player data saved to GameCenter");
    }else{
        NSLog(@"Player=%@ data NOT saved to GameCenter, error=%@", localPlayer, error.description);
    }
}];

The code above works fine on the xcode simulator, but when I try it on my iPhone I get the error code shown below. I can't figure this out. I have no control over where it saves the game data so why are the system trying to save it where it has no permission!?!
