matchmakerViewController:didFindMatch is not being called after accepting Invite

I am making a real time Game Center game, with GameKit as a new programmer, however I have run into a few road blocks.

I am able to properly initialize the local player, present the matchmaking viewController, and receive and accept invites, however, even after I accept the invite 

Code Block 
matchmakerViewController:didFindMatch 

is not called and no match is returned to me. There is a high likelihood that I did not accept the invitation correct, but according to apples developer forums I have. If someone could review this code and let me know how to have that method be called that'd be great!

let request = GKMatchRequest()
