If you are in navigation controller, you can get the VC on top.

self.navigationController?.topViewController

will return you the ViewController on top of the stack.

You can check this for other options.

To point a few:

  • var topViewController: UIViewController?
    The view controller at the top of the navigation stack.

  • var visibleViewController: UIViewController?
    The view controller associated with the currently visible view in the navigation interface.

  • var viewControllers: [UIViewController]
    The view controllers currently on the navigation stack.
