// NotificationController override func didReceiveRemoteNotification( remoteNotification: [NSObject : AnyObject], withCompletion completionHandler: ((WKUserNotificationInterfaceType) -> Void)) { // This method is called when // a remote notification needs to be presented. // Implement it if you use a dynamic // notification interface. // Populate your dynamic notification interface // as quickly as possible. // // After populating your dynamic notification // interface call the completion block. completionHandler(.Custom) //completionHandler(.Default) }
