reportNewIncomingCall completion not called

Question

The reportNewIncomingCall completion argument isn't being called, which means that I'm not getting any feedback as to why my VOIP app isn't displaying the call receiving alert.

    func reportIncomingCall(uuid: UUID, handle: String, hasVideo: Bool = false, completion: ((NSError?) -> Void)?) {
    // 1.
    let update = CXCallUpdate()
    update.remoteHandle = CXHandle(type: .phoneNumber, value: handle)
    update.hasVideo = hasVideo

    // 2.
    provider.reportNewIncomingCall(with: uuid, update: update) { error in
        if error == nil {
            // 3.
            let call = Call(uuid: uuid, handle: handle)
            self.callManager.add(call: call)
        }

        // 4.
        completion?(error as? NSError)
    }
}

I am taking this from a Ray Wanderlich tutorial.

I copied the code as exactly as possible. It works in the tutorial but not in my project.
