Change 'Return' button function to 'Done' in swift in UITextView

Question

I would like to get rid of the \"return\" function of the keyboard while the user is typing, so there are no new lines, so instead I would like the \'return\' key to function as

Answer 1

Working in Swift 4

Add this in viewDidLoad().

textField.returnKeyType = UIReturnKeyType.Done

Add this anywhere you like.

extension UITextView: UITextViewDelegate {
    public func textViewDidChange(_ textView: UITextView) {
        if text.last == "\n" { //Check if last char is newline
            text.removeLast() //Remove newline
            textView.resignFirstResponder() //Dismiss keyboard
        }
    }
}
