So, I spent two and a half years perfecting my first game for iOS, including the ability to challenge other players to beat the player's score for any given puzzle. Well, it had been working great, the Challenge view controller would allow you to send a friend request if you didn't have any... Recently, I discovered that it was no longer working. If you had friends in your list, you could still challenge them, but you could not send a challenge to any new friends. So, I have been searching online for a solution, but it seems like challenges have gone by the wayside to be replaced by strictly turn-based or multiplayer matches. I can find nothing to solve my dillema of adding friends to challenge. Also, does this "change" affect the Leaderboard filtering? If I don't have friends, but have the leaderboard set to filter friends.... I see no scores. Is the Leaderboard filter only friends deprecated too?
I also noticed that the online documentation is SORELY out of date, with many of the Game Kit topics last updated in 2016. Apple, if you are going to change stuff around, CHANGE THE DOCS TOO. </rant>
Anyway, if anyone can help, I would appreciate it. I am using GKScore challengeComposeControllerWithMessage.
