I'm not particularly good with iOS, but taking a quick look at the documentation for the PKPushRegistryDelegate it looks like your pushRegistry function definition isn't right.

It should be

func pushRegistry(_ registry: PKPushRegistry, 
    didReceiveIncomingPushWith payload: PKPushPayload, 
    forType type: PKPushType)

That is, didReceiveIncomingPushWith rather than didReceiveIncomingPushWithPayload.

Alternatively, does it have anything to do with the fact that you're casting forType to String?
