RNFIREBASE MESSENGER not working on iOS but working on Android

[DaleOC]

Push notifications are working on Android but not iOS. I have tested on a device and through TestFlight

I have done the additional setup required for iOS.

Included in index.js

import messaging from '@react-native-firebase/messaging';
// Register background handler
messaging().setBackgroundMessageHandler(async remoteMessage => {
  console.log('Hey');
  console.log('Message handled in the background!', remoteMessage);
});

const Applicaiton: () => React$Node = () => {
  useEffect(() => {
    console.log('RN Message Called on USEFFECT!');
    const unsubscribe = messaging().onMessage(async remoteMessage => {
      Alert.alert('A new FCM message arrived!', JSON.stringify(remoteMessage));
    });

    return unsubscribe;
  }, []);


async function requestUserPermission() {
    const authStatus = await messaging().requestPermission();
    const enabled =
      authStatus === messaging.AuthorizationStatus.AUTHORIZED ||
      authStatus === messaging.AuthorizationStatus.PROVISIONAL;
  
    if (enabled) {
      console.log('Authorization status:', authStatus);
    }
  }

Signing and Certificates

Push notifications on iOS definitely work. This will be a project-specific problem. It will not be possible really to provide support for it since getting it right is difficult (unfortunately)

Please search the issues and the tips-n-tricks on rnfirebase.io for important items related to background processing or foreground processing etc.

You may want to take advantage of the recently added ability to set Firebase debugging on via javascript #5606 then launch on a real device from Xcode and watch the console output from within Xcode.

Thanks Mike,

Been through the tips n tricks as well as other threads. I will look into Firbase debugging as suggested.

I have the same problem, I have registered the APNs certificates in the Firebase Console in IOS Firebase notifications arrive and the messaging().onMessage method is fired but with APNs the method does not fire, however the notifications arrive. Please help
