Change UIReturnKeyType on UITextView change

I'm trying to change the return key from default to done when the user enters a string inside my UITextView. I'm attempting to do this inside textViewDidChange(_ textView: UITextView) but the return key changes only after I tap inside another UITextView (with a different return key type) and come back to the original text view. It does not happen immediately, after the string has been entered.

func textViewDidChange(_ textView: UITextView) {
    myTextView.returnKeyType = myTextView.text.isEmpty ? .default : .done
}

What am I doing wrong?

I solved it by setting myTextView.enablesReturnKeyAutomatically = true. It grays out the 'Done' button and makes it blue when the user starts typing!

You cant update the keyboard once it is open. You can update it by just closing and opening at the same time. So put this at the bottom

self.view.endEditing(true)
textView.becomeFirstResponder()

Try this

func textViewDidChange(_ textView: UITextView) {

   textView.returnKeyType = ert..text.isEmpty ? .default : .done

   textView.resignFirstResponder()

   textView.becomeFirstResponder()
}
