GameCenter turnbased match making using player group

This is the constructor method of TurnBasedMatchesController.StartMatch()

public static void StartMatch(
	uint minPlayers,
	uint maxPlayers,
	Player[] playersToInvite = null,
	bool showExistingMatches = true
)

and this is the constructor method of RealTimeMatchesController.StartMatch()

public static void StartMatch(
	uint minPlayers,
	uint maxPlayers,
	uint playerGroup = 0,
	uint playerAttributes = 0,
	Player[] playersToInvite = null
)

which shows that realtime matches support an argument for player group in game center while turnBased matches do not. Can we solve this issue with the existing plugin version?

We have solve this issue by downloading your high level uncompiled code files from GitHub - vitapoly/u3dxt: Source code to the iOS SDK plugin from U3DXT for Unity3D .
We simply edited the method to use GKMatchRequest.playerGroup in your method TurnBasedMatchesController.StartMatch().
