I'm trying to explain to someone there's 3 options for
Specifies an appropriate autocorrection behavior for the current script system.
default says to use whatever value is set in the iOS Settings app under General -> Keyboard. If the "Auto-correction" setting is enabled and the
UITextAutocorrectionType is set to

no explicitly says not to do any autocorrection regardless of the "Auto-correction" setting.
yes explicitly says to do autocorrect regardless of the "Auto-correction" setting.
