Firebase Cloud Messaging ne crée pas de notifications push mais récupère des informations

Je travaillais à travers ce tutoriel ( https://www.youtube.com/watch?v=JsWHzU1DxjM ) pour essayer de mettre des notifications Push dans mon application iOS. J'ai réussi à obtenir le certificat pour APNS et à activer les fonctionnalités "Notification push" et "Modes d'arrière-plan". En outre, Firebase est capable d’obtenir les informations de la notification lorsque j’en envoie une depuis la console Firebase. Cependant, lorsque l'application est exécutée en arrière-plan, les notifications de bannière n'apparaissent jamais. J'ai l'impression que j'ai peut-être eu un problème pour convertir le didacticiel d'Objective-C en Swift, car il était en Objective-C, mais je n'en suis pas sûr. Je mets ma classe AppDelegate et la sortie du programme si cela aide du tout.

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

var window: UIWindow?

func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {

    connectToFcm()

    NSNotificationCenter.defaultCenter().addObserver(
        self,
        selector: #selector(tokenRefreshCallback),
        name: kFIRInstanceIDTokenRefreshNotification,
        object: nil)

    let allNotificationTypes = UIUserNotificationType(arrayLiteral: UIUserNotificationType.Sound, UIUserNotificationType.Alert, UIUserNotificationType.Badge)
    let settings = UIUserNotificationSettings(forTypes: allNotificationTypes, categories: nil)
    application.registerUserNotificationSettings(settings)
    application.registerForRemoteNotifications()
    return FBSDKApplicationDelegate.sharedInstance().application(application, didFinishLaunchingWithOptions: launchOptions)
}

func application(application: UIApplication, openURL url: NSURL, sourceApplication: String?, annotation: AnyObject) -> Bool {
    return FBSDKApplicationDelegate.sharedInstance().application(application, openURL: url, sourceApplication: sourceApplication, annotation: annotation)
}

override init() {
    FIRApp.configure()
    FIRDatabase.database().persistenceEnabled = false
}

func applicationWillResignActive(application: UIApplication) {
    // Sent when the application is about to move from active to inactive state. This can occur for certain types of temporary interruptions (such as an incoming phone call or SMS message) or when the user quits the application and it begins the transition to the background state.
    // Use this method to pause ongoing tasks, disable timers, and throttle down OpenGL ES frame rates. Games should use this method to pause the game.
}

func applicationDidEnterBackground(application: UIApplication) {
    // Use this method to release shared resources, save user data, invalidate timers, and store enough application state information to restore your application to its current state in case it is terminated later.
    FIRMessaging.messaging().disconnect()
    print("Disconnected from FCM.")
    // If your application supports background execution, this method is called instead of applicationWillTerminate: when the user quits.
}

func applicationWillEnterForeground(application: UIApplication) {
    connectToFcm()
    // Called as part of the transition from the background to the active state; here you can undo many of the changes made on entering the background.
}

func applicationDidBecomeActive(application: UIApplication) {
    // Restart any tasks that were paused (or not yet started) while the application was inactive. If the application was previously in the background, optionally refresh the user interface.
}

func applicationWillTerminate(application: UIApplication) {
    //try! FIRAuth.auth()!.signOut()
}

func connectToFcm() {
    FIRMessaging.messaging().connectWithCompletion { (error) in
        if (error != nil) {
            print("Unable to connect with FCM. \(error)")
        } else {
            print("Connected to FCM.")
        }
    }
}


func tokenRefreshCallback(notification: NSNotification) {
    let refreshedToken = FIRInstanceID.instanceID().token()
    print("InstanceID token: \(refreshedToken)")

    // Connect to FCM since connection may have failed when attempted before having a token.
    if (refreshedToken != nil)
    {
        connectToFcm()
    }

    }

func application(application: UIApplication, didReceiveRemoteNotification userInfo: [NSObject : AnyObject],
                 fetchCompletionHandler completionHandler: (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

    // Print message ID.
    print("\(userInfo)")
    //print("Message ID: \(userInfo["gcm.message_id"]!)")
    NSNotificationCenter.defaultCenter().postNotificationName("name", object: userInfo)

    // Print full message.
    print("%@", userInfo)
}
}

Ajoutez FirebaseAppDelegateProxyEnabled, tapez "Boolean", valeur "NO" dans votre info.plist:

Vous manquez les méthodes UNUserNotificationDelegate qui vous permettent d'obtenir des notifications. 

extension NotificationManager: UNUserNotificationCenterDelegate {

    func userNotificationCenter(_ center: UNUserNotificationCenter, didReceive response: UNNotificationResponse, withCompletionHandler completionHandler: () -> Void) {

        switch response.actionIdentifier {

        // NotificationActions is a custom String enum I've defined
        case NotificationActions.HighFive.rawValue:
            print("High Five Delivered!")
        default: break
        }
    }

    func userNotificationCenter(_ center: UNUserNotificationCenter, willPresent notification: UNNotification, withCompletionHandler completionHandler: (UNNotificationPresentationOptions) -> Void) {

        // Delivers a notification to an app running in the foreground.
    }
}

Ces deux méthodes de délégation remplacent les anciennes méthodes que vous utilisez actuellement pour recevoir (c'est-à-dire didReceiveRemoteNotification). Voir ce tutoriel pour plus d'informations: http://cleanswifter.com/ios-10-local-notifications/
