How to hide the navigation bar using hidesBarsOnSwipe
Swift version: 5.0
iOS gives UINavigationController a simple property that masks some complex behavior. If you set hidesBarsOnSwipe to be true for any UINavigationController, then iOS automatically adds a tap gesture recognizer to your view to handle hiding (and showing) the navigation bar as needed. This means you can mimic Safari's navigation bar behavior in just one line of code, like this:
navigationController?.hidesBarsOnSwipe = trueRemember to set this back to false when you want to stop the behavior from happening.
