Not getting the APNS token from iOS

Question

I am using Firebase for Push Notification in my Flutter App. I didn't receive any APNS token from iOS. Whether the IOS simulator provides an APNS token or not or if it requires a Physical Device. AppDelegate.swift code.

import UIKit
import Flutter
import UserNotifications
import Firebase

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    if #available(iOS 10.0, *) {
           let center  = UNUserNotificationCenter.current()

           center.requestAuthorization(options: [.sound, .alert, .badge]) { (granted, error) in
               if error == nil{
                DispatchQueue.main.async {
                  UIApplication.shared.registerForRemoteNotifications()
                }
               }
           }

       }
       else {
           UIApplication.shared.registerUserNotificationSettings(UIUserNotificationSettings(types: [.sound, .alert, .badge], categories: nil))
           UIApplication.shared.registerForRemoteNotifications()
       }
    FirebaseApp.configure()
    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }
}

Tell me one more thing whether the IOS simulator provides an APNS token or not or if it requires a Physical Device. — Wasiq Hussain, Nov 08 '21 at 12:20

You need to test registering remote notification on real device, if you run on simulator ou will get this error: "[0] (null) "NSLocalizedDescription" : "remote notifications are not supported in the simulator".

Also I want to know that APNS token also generated on Real Device?? – Wasiq Hussain Nov 08 '21 at 12:42
I ran my project on real device vs on simulator. On real device, the APN token was generated, on simulator APN token was not generated and ended with above error – Mr.SwiftOak Nov 08 '21 at 12:43

I can confirm what Mr.SwiftOak said, you can use the getAPNSToken function only on a real iOS device, otherwise it will return null on simulators.
