let keyboardEndFrameScreenCoordinates = (userInfo[UIResponder.keyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
    let keyboardEndFrame = self.view.convert(keyboardEndFrameScreenCoordinates, to: view.window)

    if notification.name == Notification.Name.UIResponder.keyboardWillHideNotification {
        textView.contentInset = UIEdgeInsets.zero
    } else {
        textView.contentInset = UIEdgeInsets(top: 0, left: 0, bottom: keyboardEndFrame.height, right: 0)
        textView.scrollIndicatorInsets = textView.contentInset
    }

    textView.scrollRangeToVisible(textView.selectedRange)
}
 Can anyone help me out, please?
