Discussion
For a receiver that is a control with editable text (such as an NSTextField object), the field editor is sized to aRect and is then activated and editing begins. It’s the responsibility of the delegate to end editing when responding to control(_:textShouldEndEditing:). Upon ending the editing session, the delegate should remove any data from the field editor.
