swift Xcode中Prepare()的反义词是什么

override func prepare(for segue: UIStoryboardSegue, sender: Any?) {
        if segue.identifier == Storyboards.AuthenticationStoryboard.Segues.forgotPasswordSegue {
            guard let navigationController = segue.destination as? UINavigationController else { return }
            guard let forgotPasswordViewController = navigationController.viewControllers.first as? ForgotPasswordEmailViewController else { return }
            forgotPasswordViewController.viewModel.email.value = viewModel.model.email.value
        }
        if segue.identifier == Storyboards.AuthenticationStoryboard.Segues.showPhoneViewSegue {
            guard let destinationViewController = segue.destination as? EnterPhoneViewController else { return }
            destinationViewController.successFallbackViewController = self
        }
    }

这是当前被覆盖的准备功能。据我所知，这个函数是在执行segue之前调用的。类似地，是否有任何函数可以编写，以便在完成SEGUE后执行指令。
