J'ai implémenté Firebase Cloud Messaging conformément aux instructions fournies sur leur site Web. Alors, quand je produis notification ici: 
didReceiveRemoteNotification ne reçoit pas de notifications via FCM
Et dans AppDelegate.swift J'ai ajouté la fonction didReceiveRemoteNotification comme:
func application(_ application: UIApplication, didReceiveRemoteNotification userInfo: [AnyHashable: Any],
fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void) {
Messaging.messaging().appDidReceiveMessage(userInfo)
print(userInfo)
completionHandler(UIBackgroundFetchResult.newData)
}
D'autres méthodes que j'ai mis en place sont func messaging(_ messaging: Messaging, didRefreshRegistrationToken fcmToken: String) func messaging(_ messaging: Messaging, didReceive remoteMessage: MessagingRemoteMessage) func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken: Data)
Attendu que mon didFinishLaunchingWithOptions a:
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()
FirebaseApp.configure()
NotificationCenter.default.addObserver(self, selector: #selector(self.tokenRefreshNotification), name: NSNotification.Name.InstanceIDTokenRefresh, object: nil)
return true
