dismiss a navigation controller in swift

To dismiss a UINavigationController in Swift, you can call the dismiss method on the navigation controller's presentingViewController property. This will dismiss the navigation controller and any view controllers that it has presented.

Here's an example:

main.swift
// Assuming you have a reference to the navigation controller
navigationController?.presentingViewController?.dismiss(animated: true, completion: nil)

3 lines

This code will dismiss the navigation controller and any presented view controllers, with an animated transition. If you want to do any additional clean-up or updates after the dismissal, you can provide a completion block to the dismiss method.
