Firebase notifications not working in iOS 11

Question

I'm developing an app that uses Firebase push notifications. It worked well until I tried in iOS 11. Using an iphone with ios 11 the notifications don't arrive. Here's my code:

- (void)application:(UIApplication *)application    didReceiveRemoteNotification:(NSDictionary *)userInfo   fetchCompletionHandler:(void (^)   (UIBackgroundFetchResult))completionHandler {       //Manage notification   }  - (void)userNotificationCenter:(UNUserNotificationCenter *)center    willPresentNotification:(UNNotification *)notification      withCompletionHandler:(void (^)(UNNotificationPresentationOptions))completionHandler{     //Manage notification } 

Neither of the methods are called.

Thanks for the help!

Answer 1

This is an issue with Firebase. It seems to be related to a recent update of theirs instead of iOS 11. They are working on a fix for it.

In the meantime if you add pod 'FirebaseInstanceID', '2.0.0' to your podfile it will fix it.

You need to implement UNUserNotificationCenterDelegate

 extension AppDelegate: UNUserNotificationCenterDelegate {         func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: @escaping (UNNotificationPresentationOptions) -> Void) {             completionHandler(.alert)         }     } 

and set it to UNUserNotificationCenter object inside didFinishLaunchingWithOptions

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?) -> Bool {       UNUserNotificationCenter.current().delegate = self       return true }
