Powiadomienie lokalne w WatchOS 3

Question

Używam wersji beta WatchOS 3 i próbuję zainicjować lokalne powiadomienie na zegarku. Interfejs to tylko jeden przycisk, który wywołuje metodę "buttonPushed" w poniższym kodzie. Aplikacja działa dobrze, ale nigdy nie otrzymuję powiadomienia. Struktura aplikacji jest domyślna z Xcode 8 dla aplikacji WatchKit.

Ten kod jest w pliku InterfaceController.swift przedłużenia WatchKit

jestem brakuje czegoś zupełnie oczywiste?

@IBAction func buttonPushed() { 
     sendMyNotification() 
    } 

    func sendMyNotification(){ 
     if #available(watchOSApplicationExtension 3.0, *) { 

      let center = UNUserNotificationCenter.current() 

      center.requestAuthorization(options: [.alert, .sound]) { (granted, error) in 
       // Enable or disable features based on authorization. 
      } 


      let content = UNMutableNotificationContent() 
      content.title = NSString.localizedUserNotificationString(forKey: "Hello!", arguments: nil) 
      content.body = NSString.localizedUserNotificationString(forKey: "Hello_message_body", arguments: nil) 
      content.sound = UNNotificationSound.default() 
      content.categoryIdentifier = "REMINDER_CATEGORY" 
      // Deliver the notification in five seconds. 
      let trigger = UNTimeIntervalNotificationTrigger.init(timeInterval: 5, repeats: false) 
      let request = UNNotificationRequest.init(identifier: "FiveSecond", content: content, trigger: trigger) 

      // Schedule the notification. 

      center.add(request ,withCompletionHandler: nil) 



     } else { 
      // Fallback on earlier versions 
     } 


    }

Zgodnie z this. Za każdym razem należy podać unikalny i nowy identyfikator żądania.

Mine:

let id = String(Date().timeIntervalSinceReferenceDate) 
let request = UNNotificationRequest(identifier: id, content: content, trigger: trigger)

Lokalne watchOS powiadomień Swift 4,0

var content = UNMutableNotificationContent() 
content.title = "ALERT !" 
content.body = msg 
content.sound = UNNotificationSound.default() as? UNNotificationSound 
// Time 
var trigger: UNTimeIntervalNotificationTrigger? 
trigger = UNTimeIntervalNotificationTrigger(timeInterval: 1, repeats: false) 
// Actions 
var snoozeAction = UNNotificationAction(identifier: "Track", title: "Track", options: .foreground) 

var category = UNNotificationCategory(identifier: "UYLReminderCategory", actions: [snoozeAction], intentIdentifiers: [] as? [String] ?? [String](), options: .customDismissAction) 
var categories = Set<AnyHashable>([category]) 

center.setNotificationCategories(categories as? Set<UNNotificationCategory> ?? Set<UNNotificationCategory>()) 

content.categoryIdentifier = "UYLReminderCategory" 

var identifier: String = stringUUID() 

var request = UNNotificationRequest(identifier: identifier, content: content, trigger: trigger) 

center.add(request, withCompletionHandler: {(_ error: Error?) -> Void in

Swift 4 prosty kod

let content = UNMutableNotificationContent() 
    content.title = "How many days are there in one year" 
    content.subtitle = "Do you know?" 
    content.body = "Do you really know?" 
    content.badge = 1 

    let trigger = UNTimeIntervalNotificationTrigger(timeInterval: 5, repeats: false) 
    let request = UNNotificationRequest(identifier: "timerDone", content: content, trigger: trigger) 
    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
