IOS push notification not showing

Question

My application has a connection to the Firebase server, also for sending push notifications. Now I want to go even further and add action to the notifications. After many lessons, it still does not work for me. The action button is not displayed, as you can see here:

Here is my code:

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {
    UIApplication.shared.applicationIconBadgeNumber = 0
    FirebaseApp.configure()
    registerForPushNotifications()
    return true
}

func registerForPushNotifications() {
    UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) {
        (granted, error) in
        print("Permission granted: \(granted)")

        guard granted else { return }

        let viewAction = UNNotificationAction(identifier: "addToCal",
                                              title: "Zum Kalender hinzufügen",
                                              options: [.foreground])

        let newsCategory = UNNotificationCategory(identifier: "NEW_SESSION",
                                                  actions: [viewAction],
                                                  intentIdentifiers: [],
                                                  options: [])
        UNUserNotificationCenter.current().setNotificationCategories([newsCategory])
        self.getNotificationSettings()
    }
}

func getNotificationSettings() {
    UNUserNotificationCenter.current().getNotificationSettings { (settings) in
        print("Notification settings: \(settings)")
        guard settings.authorizationStatus == .authorized else { return }
        DispatchQueue.main.async {
            UIApplication.shared.registerForRemoteNotifications()
        }
    }
}

As I saw in this tutorial, I also added a category key with the value "NEW_SESSION" to the push notification being sent, but it also doesn't work.

Update: I noticed that the “category” key is being passed through a notification, so it’s just a matter of dealing with this correctly. The userInfo dictionary looks like this:

{ "aps" : { 
"alert" : { 
"body" : "This notification has no action", 
"title" : "Test", 
} 
}, 
"category" : "NEW_SESSION" 
}

. 3D . / .

UNUserNotificationCenter.current().requestAuthorization(options: [.alert, .sound, .badge]) {
            (granted, error) in
            print("Permission granted: \(granted)")

            guard granted else { return }

            let action = UNNotificationAction(identifier: "addToCal", title: "Zum Kalender hinzufügen", options: [])
            let category = UNNotificationCategory(identifier: "NEW_SESSION", actions: [action], intentIdentifiers: [], options: [])
            UNUserNotificationCenter.current().setNotificationCategories([category])

            self.getNotificationSettings()
        }

UNUserNotificationCenterDelegate .

@available(iOS 10, *)
extension AppDelegate : UNUserNotificationCenterDelegate {

    // Receive displayed notifications for iOS 10 devices.
    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                willPresent notification: UNNotification,
                                withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {
        // Print message ID.
        // Print full message.
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        if response.actionIdentifier == "addToCal" {

            //Handel action.
        }
    }
}

:

UNUserNotificationCenter.current().delegate = self

{
    "aps" : {
              "category" : "NEW_MESSAGE_CATEGORY",
               "alert" : {
                        "body" : "Acme message received from Johnny Appleseed",
                        "title" : "Test",
                    },
               "badge" : 3,
             },
}
