title: Confusion connecting iOS portion of Flutter App to Firebase
body: <p>I'm attempting to connect the iOS portion of my Flutter app to Firebase. And as I go through the steps on Firebase - "<strong>Add Firebase to your iOS app</strong>" - I hit a step that says "<em>Add the initialization code below to your main AppDelegate class</em>" (Swift version):</p>
  
  <pre><code>import UIKit
  import Firebase
  
  @UIApplicationMain
  class AppDelegate: UIResponder, UIApplicationDelegate {
  
    var window: UIWindow?
  
    func application(_ application: UIApplication,
      didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?)
      -&gt; Bool {
      FirebaseApp.configure()
      return true
    }
  }
  </code></pre>
  
  <p>But my AppDelegate class already has this code:</p>
  
  <pre><code>import UIKit
  import Flutter
  
  @UIApplicationMain
  @objc class AppDelegate: FlutterAppDelegate {
    override func application(
      _ application: UIApplication,
      didFinishLaunchingWithOptions launchOptions: [UIApplicationLaunchOptionsKey: Any]?
    ) -&gt; Bool {
      GeneratedPluginRegistrant.register(with: self)
      return super.application(application, didFinishLaunchingWithOptions: launchOptions)
    }
  }
  </code></pre>
  
  <p>Not sure what to do. Do I replace the existing code with the code provided by Firebase or do I reconcile the two somehow?</p>
