• my application is an AndroidX application?
• I am using android/gradle.settings jetifier=true for Android compatibility?

I have fixed the issue by importing FirebaseMessaging as import FirebaseMessaging

and also done the MessagingDelegate conformance to AppDelegate class declaration. Modified AppDelegate.swift becomes

import UIKit
import React
import Firebase
import CodePush
import React_RCTAppDelegate
import ReactAppDependencyProvider
import FirebaseMessaging

@main
class AppDelegate: RCTAppDelegate, MessagingDelegate {

  override func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey : Any]? = nil) -> Bool {
        FirebaseApp.configure()
        Messaging.messaging().delegate = self
        self.moduleName = "BWReactApp"
        self.dependencyProvider = RCTAppDependencyProvider()
        self.initialProps = [:]
        return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }
    
    override func sourceURL(for bridge: RCTBridge) -> URL? {
      self.bundleURL()
    }
 
  override func bundleURL() -> URL? {
    #if DEBUG
      RCTBundleURLProvider.sharedSettings().jsBundleURL(forBundleRoot: "index")
    #else
      Bundle.main.url(forResource: "main", withExtension: "jsbundle")
    #endif
  }
}

now I just need to know if this is correct?

[mikehardy]

Where in our documentation / why are you setting the Messaging delegate? I don't recall seeing that as a step to do anywhere
