Flutter FCM iOS Issue

Question

APNS device token not set before retrieving FCM Token for Sender ID ''. Notifications to this FCM Token will not be delivered over APNS.Be sure to re-retrieve the FCM token once the APNS device token is set.

I am encountering this error.I have no idea how to solve. Can you help me?

Thanks.

Solution

Try running on a real device

Try this:

AppDelegate.swift

import UIKit
import Flutter
import Firebase
import FirebaseMessaging
import UserNotifications
@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
    var firebaseToken : String = "";
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    Messaging.messaging().delegate = self;
    FirebaseApp.configure()
    GeneratedPluginRegistrant.register(with: self)
    Messaging.messaging().isAutoInitEnabled = true;
    self.registerForFirebaseNotification(application: application);
    return true;
   // GeneratedPluginRegistrant.register(with: self)
    
  }
   override func application(_ application: UIApplication, didRegisterForRemoteNotificationsWithDeviceToken deviceToken : Data){
    print("X__APNS: \(String(describing: deviceToken))")
       Messaging.messaging().apnsToken = deviceToken;
    //Messaging.messaging().setAPNSToken(deviceToken, type:MessagingAPNSTokenType.prod )
    }
    
    override func application(_ application: UIApplication, didFailToRegisterForRemoteNotificationsWithError error: Error) {
        print("X_ERR",error);
    }
    
     func registerForFirebaseNotification(application : UIApplication){
    //    Messaging.messaging().delegate     = self;
        if #available(iOS 10.0, *) {
            //UNUserNotificationCenter.current().delegate = self ;
            let authOpt : UNAuthorizationOptions = [.alert, .badge, .sound];
            UNUserNotificationCenter.current().requestAuthorization(options: authOpt, completionHandler: {_, _ in})
            UNUserNotificationCenter.current().delegate = self ;
        }else{
            let settings : UIUserNotificationSettings = UIUserNotificationSettings(types: [.alert, .badge, .sound], categories: nil)                
            application.registerUserNotificationSettings(settings);
        }
        application.registerForRemoteNotifications();
    }
}

extension AppDelegate : MessagingDelegate{
    func messaging(_messagin : Messaging, didRecieveRegistrationToken fcmToken : String){
        self.firebaseToken = fcmToken;
        print("X__FCM: \(String(describing: fcmToken))")
    }
    func messaging(_messagin : Messaging, didRecieve remoteMessage : Any){
        //self.firebaseToken = fcmToken;
        print("REMOTE__MSG: \(remoteMessage)")
    }
    func application(_ application : UIApplication,didRecieveRemoteNotification uinfo: [AnyHashable : Any], fetchCompletionHandler completionHandler: @escaping (UIBackgroundFetchResult) -> Void){
        print("WITH__APN: \(uinfo)")
    }
}
