How do I dismiss the iOS keyboard?

Question

I have a UITextfield that i\'d like to dismiss the keyboard for. I can\'t seem to make the keyboard go away no matter what code i use.

Answer 1

To resign any text field in the app

UIApplication.shared.keyWindow?.endEditing(true)

This approach is clean and guarantied to work because the keyWindow is, by definition, the root view of all possible views displaying a keyboard (source):

The key window receives keyboard and other non-touch related events. Only one window at a time may be the key window.
