I\'m am attempting to send a Game Center invitation. Sending from the simulator to a device or from a device to the simulator results in an InviteFailed error.
What
Even though the invite functionality doesn't work in the simulator, you can still test multiplayer in the simulator using findMatchForRequest (kind of like an auto-match function):
[[GKMatchmaker sharedMatchmaker] findMatchForRequest:request withCompletionHandler:^(GKMatch *match, NSError *error)
As far as I am aware you cannot test multiplayer in the simulator. You will need two devices.
