See robingenz/capacitor-firebase-plugin-demo#299

Expected behavior

I expected to successfully retrieve the Firebase App Check token without any errors.

Reproduction

https://github.com/robingenz/capacitor-firebase-plugin-demo

Steps to reproduce

1. Open the iOS app.
2. Navigate to the screen where the Firebase App Check token is requested.
3. Check "Use Debug Provider" and click on the "Initialize" button.
4. Click on the "Get Token" button.
5. Observe the error message.

Other information

Until now, Firebase on Android and iOS is initialized automatically when the app is launched, see this example.
However, sometimes Firebase may not be initialized directly at startup. This is the case for Firebase App Check if you want to use the debug provider, see here.

let providerFactory = AppCheckDebugProviderFactory()
AppCheck.setAppCheckProviderFactory(providerFactory)

FirebaseApp.configure()
