    viewController = storyboard.instantiateViewControllerWithIdentifier("Start")

    if self.respond_to?("initializeRootViewController:forApplication:launchedWithOptions:")
      viewController = initializeRootViewController(viewController, forApplication:application, launchedWithOptions:launchOptions) 
    end

    @window = UIWindow.alloc.initWithFrame(UIScreen.mainScreen.bounds)
