Is there a way to update matchData in a GKTurnBasedMatch without sending out “Your Turn” push notifications?

There shouldn't really be a reason to update the match data during the turn. None of the other players can react until their turn, so the data only needs to be passed as play transitions from one player to another.

I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
