+  [jitsiMeet application:application didFinishLaunchingWithOptions:launchOptions];

     // Initialize Crashlytics and Firebase if a valid GoogleService-Info.plist file was provided.
   if ([FIRUtilities appContainsRealServiceInfoPlist]) {
         NSLog(@"Enabling Firebase");
 
     ViewController *rootController = (ViewController *)self.window.rootViewController;
     [jitsiMeet showSplashScreen:rootController.view];
