Push notification not triggering automatically in ios - swift

Question

I have a push notification in my ios code.The code in app delegate is as follows:
func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
FirebaseApp.configure()
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: {_, _ in })
// For iOS 10 data message (sent via FCM
Messaging.messaging().delegate = self
} else {
let settings: UIUserNotificationSettings =
UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)
application.registerUserNotificationSettings(settings)
}
application.registerForRemoteNotifications()
Messaging.messaging().delegate = self
let token = Messaging.messaging().fcmToken
print("FCM token: \(token ?? "")")
return true
}
func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) {
print(fcmToken)
}
func application(
_ application: UIApplication,
didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data
) {
let tokenParts = deviceToken.map { data in String(format: "%02.2hhx", data) }
let token = tokenParts.joined()
print("Device Token aaaa: \(token)")
Messaging.messaging().apnsToken = deviceToken
Messaging.messaging().setAPNSToken(deviceToken, type: .unknown)
viewController?.updatetoken(token: deviceToken)
}
func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
print("failed to register for remote notifications",error)
}
func messaging(_ messaging: Messaging, didReceiveRegistrationToken fcmToken: String) {
print("Firebase registration token didreceieve: \(fcmToken)")
UserDefaults.standard.set(fcmToken, forKey: "fcmToken")
let dataDict:[String: String] = ["token": fcmToken]
NotificationCenter.default.post(name: Notification.Name("FCMToken"), object: nil, userInfo: dataDict)
}
// For iOS 10 and later; do not forget to set up a delegate for UNUserNotificationCenter
func userNotificationCenter(_ center: UNUserNotificationCenter,
didReceive response: UNNotificationResponse,
withCompletionHandler completionHandler:
#escaping () -> Void) {
let userInfo = response.notification.request.content.userInfo
viewController?.receivedNotification(userinfo: userInfo as NSDictionary)
}
// For iOS versions before 10
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: #escaping (UIBackgroundFetchResult) -> Void) {
// If your application supports multiple types of push notifications, you may wish to limit which ones you send to the TwilioChatClient here
print("userinfo is",userInfo)
viewController?.receivedNotification(userinfo: userInfo as NSDictionary)
}
func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: #escaping (UNNotificationPresentationOptions) -> Void) {
print("Push notification received in foreground.")
let userInfo = notification.request.content.userInfo
completionHandler([.alert, .badge, .sound])
}
I have added a ios project in the firebase and added the sandbox and production p12 certificate to it.I tried notification using cloud messaging by selecting the bundle id from firebase and i got notification.Also, i tried notification using push try using the p12 and device token,i got notification.But i am not getting notification automatically from the app like the way in android.
What could the issue be in my code?
