Current problem

Currently this package does not work when running the Capacitor code from an iOS simulator, unless the debug flag is set when calling FirebaseAppCheck.initialize(). This is because simulators only support running with the AppCheckDebugProvider and will fail any real device checks.

Preferred solution

As per the Firebase docs, the following code could be implemented:

class MyAppCheckProviderFactory: NSObject, AppCheckProviderFactory {
  func createProvider(with app: FirebaseApp) -> AppCheckProvider? {
    #if targetEnvironment(simulator)
      // App Attest is not available on simulators.
      // Use a debug provider.
      return AppCheckDebugProvider(app: app)
    #else
      // Use App Attest provider on real devices.
      return AppAttestProvider(app: app)
    #endif
  }
}

You can already select the debug provider using the initialize method. I'm therefore closing this issue.
