Unable to get FCM token using "getToken()" method in iOS 26

[piyushlt987-del]

FCM token is not being generated on iOS 26.0 using @react-native-firebase/messaging.

The issue occurs on:

❌ iOS 26.0 Simulator
❌ iOS 26.0 Physical Device

While the same implementation works fine on:

✅ iOS 18.6
✅ iOS 26.3

Error received:

[messaging/unknown] No APNS token specified before fetching FCM Token
Steps to Reproduce
await messaging().requestPermission();
await messaging().registerDeviceForRemoteMessages();
const token = await messaging().getToken();
Expected Behavior

FCM token should be returned.

Actual Behavior
Token is null OR
Error: No APNS token specified
Environment
React Native: 0.75.3
@react-native-firebase/messaging: 21.7.1
@react-native-firebase/app: 21.7.1
@notifee/react-native: 9.1.8
Notes
Push Notifications & Background Modes enabled
APNS token is not being received on iOS 26.0
Same setup works on other iOS versions
Question

Is this a known issue with iOS 26.0, or is there any workaround?

I am facing an issue where the FCM token is not generated on iOS 26 using messaging().getToken() in my React Native project
Project setup: React Native 0.75.3, React 18.3.1, @react-native-firebase/app and @react-native-firebase/messaging 21.7.1
The same implementation works correctly on Android and other iOS versions like 18.6 and 26.3
On iOS 26, messaging().getToken() always returns null
The issue occurs on both simulator and real device
Notification permission is requested using messaging().requestPermission() and is granted successfully
No errors are shown in the console while fetching the token
Foreground, background, and notification open handlers are properly set up and working
All other notification functionalities seem to be working fine
Need to know if there is any known issue, missing configuration, or additional setup required specifically for iOS 26 to retrieve the FCM token

I am facing error :
This method is deprecated (as well as all React Native Firebase namespaced API) and will be removed in the next major release as part of move to match Firebase Web modular SDK API. Please see migration guide for more details: https://rnfirebase.io/migrating-to-v22 Please use getApp() instead.

The reason you are getting this error (Not really an error, more of a warning) is because you are using the name-spaced API which is being deprecated and will eventually be completely removed so you will need to use the Modular API, here is an idea of how you might achieve this:

const loadToken = async () => {
    setBusy(true);
    setError(null);
    try {
      if (Platform.OS === 'ios') {
        await registerDeviceForRemoteMessages(messaging);
      }
      const authStatus = await requestPermission(messaging);
      const ok =
        authStatus === AuthorizationStatus.AUTHORIZED ||
        authStatus === AuthorizationStatus.PROVISIONAL;
      if (!ok) {
        setError('Notification permission not granted');
        return;
      }
      const t = await getToken(messaging);
      setToken(t);
    } catch (e: unknown) {
      setError(e instanceof Error ? e.message : String(e));
    } finally {
      setBusy(false);
    }
  };

For seeing usage with the modular API, i highly suggest checking out these docs: https://firebase.google.com/docs/reference/js?_gl=1*6l9brf*_up*MQ..*_ga*MTU5MDk4OTI1My4xNzc0MjYyNjY0*_ga_CW55HF8NVT*czE3NzQyNjI2NjQkbzEkZzAkdDE3NzQyNjI2NjQkajYwJGwwJGgw
