Not receiving push notifications when running Flutter app on iOS

[CamronLDNF]

I'm using clevertap_plugin: 1.3.0.

I have followed your Flutter sdk documentation and read through the Push Notifications sections of your Android sdk and iOS sdk documentation as well. When I send notifications, they arrive on Android but not on iOS. How do I resolve this?

I saw this earlier issue that seems to be related. It says to send our APNS token first, but how do we do that? Unfortunately we don't have iOS experience, so it's a bit murky on how to implement that.

Your iOS sdk documentation on Push Notifications states "If you automatically integrated the SDK in the quick start guide, you have already enabled push notification support." Obviously that is not the case.

Please note: we already have FCM integrated in our app, which has APNS integrated out of the box, so we are receiving our normal notifications just fine on both Android and iOS. It's just this CleverTap setup for iOS notifications that isn't working.

I have provided screenshots and code below.

As a side note, If you want this plugin to be purely a Flutter plugin without requiring iOS or Android knowhow, why not just use FCM for iOS notifications as well? FCM already has APNS integration out of the box, which Flutter developers use.

The notifications are sent correctly

AppDelegate.swift

import UIKit
import Flutter
import CleverTapSDK
import clevertap_plugin

@UIApplicationMain
@objc class AppDelegate: FlutterAppDelegate {
  override func application(
    _ application: UIApplication,
    didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?
  ) -> Bool {
    
    CleverTap.autoIntegrate()
    CleverTapPlugin.sharedInstance()?.applicationDidLaunch(options: launchOptions)
    
    if #available(iOS 10.0, *) {
      UNUserNotificationCenter.current().delegate = self as? UNUserNotificationCenterDelegate
    }

    GeneratedPluginRegistrant.register(with: self)
    return super.application(application, didFinishLaunchingWithOptions: launchOptions)
  }

}

main.dart (I've basically just copied what you have in your example)

  // CleverTapPlugin.createNotificationChannel("fluttertest", "Flutter Test", "Flutter Test", 3, true); // We already have an Android notification channel set up
  CleverTapPlugin.initializeInbox();
  CleverTapPlugin.registerForPush(); //only for iOS
}

  if (!mounted) return;

Hey @CamronLDNF This looks like an integration issue. Request you to raise a support ticket from the CleverTap dashboard so that we can further deep dive into this issue and assist you.
