防止ViewController切换回上一个

我有一个简单的示例iOS应用程序,有两个视图控制器( UIViewController )如下所述。

//HomeViewController
import UIKit

class HomeViewController: UIViewController {
    // MARK: - IBAction
    @IBAction func goSecondTapped(_ sender: UIButton) {
        let storyboard = UIStoryboard(name: "Main", bundle: nil)
        if let controller = storyboard.instantiateViewController(withIdentifier: "SecondNavigator") as? UINavigationController {
            if let viewController = controller.topViewController as? SecondViewController {
                self.navigationController?.pushViewController(viewController, animated: true)
            }
        }
    }
    
    
    // MARK: - Life cycle
    override func viewDidLoad() {
       super.viewDidLoad()
    }
}

//SecondViewController
import UIKit

class SecondViewController: UIViewController {
    // MARK: - Life cycle
    override func viewDidLoad() {
       super.viewDidLoad()
    }
}

所以我只想在点击按钮时切换到SecondViewController(转到Second)。问题是,如果我只是用手指从左向右滑动第二个视图,我就可以在不点击左上角的“后退”按钮的情况下返回HomeViewController。有什么办法可以防止这种情况吗?我只想在点击“返回”时返回HomeViewController。谢谢。
