如何在没有故事板id的swift中为导航控制器设置根视图控制器。并仅使用viewcontroller名称导航到其他视图

func application(_ application: UIApplication, didFinishLaunchingWithOptions launchOptions: [UIApplication.LaunchOptionsKey: Any]?) -> Bool {
    // 创建根视图控制器
    let rootViewController = YourRootViewController()
    
    // 创建导航控制器，并将根视图控制器设置为导航控制器的根视图
    let navigationController = UINavigationController(rootViewController: rootViewController)
    
    // 设置导航控制器为应用程序的根视图控制器
    window?.rootViewController = navigationController
    window?.makeKeyAndVisible()
    
    return true
}

func navigateToOtherViewController() {
    let otherViewController = OtherViewController()
    navigationController?.pushViewController(otherViewController, animated: true)
}
