Issue on IOS - The default Firebase app has not yet been configured.

[bsprengelmeijer]

I have the following message on my iOS build when I run the application:

The default Firebase app has not yet been configured. Add `FirebaseApp.configure()` to your application initialization.
This can be done in in the App Delegate's application(_:didFinishLaunchingWithOptions:)` (or the `@main` struct's initializer in SwiftUI).

If I add [FIRApp configure]; to my AppDelegate.m file the build works and the message is gone, but I get no permission prompt on iOS.

I have use the following code:

cordova.plugins.firebase.messaging.requestPermission({forceShow: false}).then((permission) => {
    if (permission) {
          console.log('permission');
    } else {
          console.log('no permission');
    }
}

I don't get any console.logs in Xcode

My issue was not having the requestPermission inside of the deviceReady eventListener (vue-cordova application)
