Push Notification from firebase console iOS 12.2 not working

Push notifications not working at all. I have tried all the possible measures so far:

This is the code that i have tried:

In didFinishLaunchingWithOptions

FirebaseApp.configure()

if #available(iOS 10.0, *) {
    let center = UNUserNotificationCenter.current()
    center.delegate = self
    center.requestAuthorization(options: [.badge, .alert, .sound]) {
        (granted, error) in
        if granted {
            DispatchQueue.main.async {
                application.registerForRemoteNotifications()
                //UIApplication.shared.registerForRemoteNotifications()
            }
        } else {
            //print("APNS Registration failed")
            //print("Error: \(String(describing: error?.localizedDescription))")
        }
    }
} else {
    let type: UIUserNotificationType = [UIUserNotificationType.badge, UIUserNotificationType.alert, UIUserNotificationType.sound]
    let setting = UIUserNotificationSettings(types: type, categories: nil)
    application.registerUserNotificationSettings(setting)
    application.registerForRemoteNotifications()
    //UIApplication.shared.registerForRemoteNotifications()
}

Then the register and fail method:

private func application(application: UIApplication,
                 didRegisterForRemoteNotificationsWithDeviceToken deviceToken: NSData) {
    Messaging.messaging().apnsToken = deviceToken as Data
    print("Registered Notification")
}

func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {

        print(error.localizedDescription)
        print("Not registered notification")
}

@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) {
        let userInfo = notification.request.content.userInfo

        // With swizzling disabled you must let Messaging know about the message, for Analytics
        // Messaging.messaging().appDidReceiveMessage(userInfo)

        // Print message ID.
        if let messageID = userInfo["gcm.message_id"] {
            print("Message ID: \(messageID)")
        }

        // Print full message.
        print(userInfo)

        // Change this to your preferred presentation option
        completionHandler([])
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter,
                                didReceive response: UNNotificationResponse,
                                withCompletionHandler completionHandler: @escaping () -> Void) {
        let userInfo = response.notification.request.content.userInfo
        // Print message ID.
        if let messageID = userInfo["gcm.message_id"] {
            print("Message ID: \(messageID)")
        }

        // Print full message.
        print(userInfo)

        completionHandler()
    }
}

Note:

  • I have tried it on real device no push notifications so far.
  • I have double checked the certificates and regenerated the provisioning file after turning on the push notifications in capabilities.
  • I have also added background modes -> remote notifications on.
  • I have tried with legacy build also no luck.
  • I have tried reinstalling apps many times not working.
  • FirebaseAppDelegateProxyEnabled is set to NO in plist still no luck.
  • Also updated the pods still no luck.
  • .p12 certificate is at the firebase console, still not working.

Trying from last 1 week with different projects with different authentication methods with Apple key i have also tried still no luck.

here is the code i have used to generate push notification hope this helps you out.

put the whole following code in ur appdelegate.

Imported Libraries

 import Firebase
import FirebaseMessaging
import UserNotifications
import FirebaseInstanceID
import UserNotifications

add MessagingDelegate to ur appdelegate.

then

In didFinishLaunchingWithOptions

 if #available(iOS 10.0, *) {
        // For iOS 10 display notification (sent via APNS)
        UNUserNotificationCenter.current().delegate = self

        let authOptions: UNAuthorizationOptions = [.alert, .badge, .sound]
        UNUserNotificationCenter.current().requestAuthorization(options: authOptions,
                                                                completionHandler: { (bool, err) in

        })

    } else {

        let settings: UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
        application.registerUserNotificationSettings(settings)

    }

    application.registerForRemoteNotifications()
    UIApplication.shared.applicationIconBadgeNumber = 0

    FirebaseApp.configure()
    // [START set_messaging_delegate]
    Messaging.messaging().delegate = self
    let token = Messaging.messaging().fcmToken
    print("FCM token: \(token ?? "")")

Then Add these Two function 

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any]) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification

    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)

    // Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    // Print full message.
    print(userInfo)
}

func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
                 fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
    // If you are receiving a notification message while your app is in the background,
    // this callback will not be fired till the user taps on the notification launching the application.
    // TODO: Handle data of notification

    // With swizzling disabled you must let Messaging know about the message, for Analytics
    // Messaging.messaging().appDidReceiveMessage(userInfo)

    // put your json parameters here Print message ID.
    if let messageID = userInfo[gcmMessageIDKey] {
        print("Message ID: \(messageID)")
    }

    if let msg = userInfo["desc"] as? String
    {
        let title = userInfo["noti_title"] as? String
        createNotification(message: msg, title: title ?? "" )

    }

    // Print full message.
    print(userInfo)

    completionHandler(UIBackgroundFetchResult.newData)
}


func createNotification(message: String, title: String) {

    let content = UNMutableNotificationContent()
    content.title =  title
    content.body = message


    let triger = UNTimeIntervalNotificationTrigger(timeInterval: 2, repeats: false )
    let request = UNNotificationRequest(identifier: "TextMessage", content: content, trigger: triger)



    UNUserNotificationCenter.current().add(request, withCompletionHandler: nil)
}

Then add these functions to get FCMToken 

    func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data) {
        print("APNs token retrieved: \(deviceToken)")

        // With swizzling disabled you must set the APNs token here.
        if let refreshedToken = InstanceID.instanceID().token() {
            print("InstanceID token: \(refreshedToken)")

        }
        let tokenT = deviceToken.map { String(format: "%02.2hhx", $0) }.joined()
        print(tokenT)
        guard let token = InstanceID.instanceID().token() else {return}
        AppDelegate.DEVICEID = token
        print(token)
        UserDefaults.standard.set(token, forKey: "token")

        connectToFCM()


    }
    func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
        guard  let newToken = InstanceID.instanceID().token() else {return}
        AppDelegate.DEVICEID = newToken
        UserDefaults.standard.set(newToken, forKey: "token")

        connectToFCM()
    }
    func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) {
        print("Received data message: \(remoteMessage.appData)")
        print(remoteMessage.appData["notification"]!)
//        let info = response.notification.request.content.userInfo

//        if let message = info["messages"] {
//            print(message)
//        }
    }
    func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
        print("Firebase registration token: \(fcmToken)")
        UserDefaults.standard.set(fcmToken, forKey: "token")




    }

then add the following extention in your app delegate

extension AppDelegate : UNUserNotificationCenterDelegate {

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

        let userInfo = notification.request.content.userInfo

        if let messageID = userInfo[gcmMessageIDKey] {
            print("Message ID: \(messageID)")
        }

        print(userInfo)

        // Change this to your preferred presentation option
        completionHandler([.alert,.badge,.sound])
    }


    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: @escaping () -> Void) {
        let application = UIApplication.shared

        if(application.applicationState == .active){
            print("user tapped the notification bar when the app is in foreground")

            window = UIWindow(frame: UIScreen.main.bounds)
            window?.makeKeyAndVisible()

            //        let layout = UICollectionViewFlowLayout()
            window?.rootViewController = UINavigationController(rootViewController: NotificationViewController())


        }

        if(application.applicationState == .inactive)
        {
            print("user tapped the notification bar when the app is in background")
            window = UIWindow(frame: UIScreen.main.bounds)
            window?.makeKeyAndVisible()

            //        let layout = UICollectionViewFlowLayout()
            window?.rootViewController = UINavigationController(rootViewController: NotificationViewController())

        }

        /* Change root view controller to a specific viewcontroller */
        // let storyboard = UIStoryboard(name: "Main", bundle: nil)
        // let vc = storyboard.instantiateViewController(withIdentifier: "ViewControllerStoryboardID") as? ViewController
        // self.window?.rootViewController = vc

        completionHandler()
    }

    func connectToFCM()
    {
        Messaging.messaging().shouldEstablishDirectChannel = true
    }
    func initializeNotificationServices() -> Void {
        let settings = UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil)
        UIApplication.shared.registerUserNotificationSettings(settings)

        // This is an asynchronous method to retrieve a Device Token
        // Callbacks are in AppDelegate.swift
        // Success = didRegisterForRemoteNotificationsWithDeviceToken
        // Fail = didFailToRegisterForRemoteNotificationsWithError
        UIApplication.shared.registerForRemoteNotifications()
    }

}

hoping this will help you out.
