Swift version: 5.2
Showing the keyboard on an iPhone dramatically reduces how much space you have available, which is particularly annoying if the user is trying to type into a multi-line text view.
One simple way you can free up space is by setting to true the
hidesBarsWhenKeyboardAppears property of your navigation controller – that will cause the navigation bar and any toolbars to hide themselves when the keyboard is shown.
Use this code to enable it:
navigationController?.hidesBarsWhenKeyboardAppears = true
