Answer 1

You can remove text from back button using a delegate method of UINavigationController.

class CustomNavigationController: UINavigationController {

    override func viewDidLoad() {
        super.viewDidLoad()
        self.delegate = self
    }

}

extension CustomNavigationController: UINavigationControllerDelegate {
    
    func navigationController(_ navigationController: UINavigationController, willShow viewController: UIViewController, animated: Bool) {
        viewController.navigationItem.backBarButtonItem = UIBarButtonItem(title: String(), style: .plain, target: nil, action: nil)
    }
    
}
