Swift version: 5.2
If you want to let users clear their entry on a
UITextField, the standard approach is to add a clear button to the right edge of the text field. This can be done in two ways, depending on what effect you want:
textField.clearButtonMode = .always textField.clearButtonMode = .whileEditing
The first will always show the clear button, and the second will only show it while the user is editing the text.
