Scroll UITextField above Keyboard in a UITableViewCell on a regular UIViewController

I have tried most of the examples here on StackOverflow. I also used Apple\'s. The problem I seem to have with them is that they don\'t account for the UITextField being in

jqgsninimo's solution updated to 4.2. Works on iOS 12.0.

Swift 4.2

override func viewWillAppear(_ animated: Bool) {
    super.viewWillAppear(animated)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardDidShow(with:)), name: UIResponder.keyboardDidShowNotification, object: nil)
    NotificationCenter.default.addObserver(self, selector: #selector(keyboardWillHide(with:)), name: UIResponder.keyboardWillHideNotification, object: nil)
}

override func viewWillDisappear(_ animated: Bool) {
    super.viewWillDisappear(animated)
    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardDidShowNotification, object: nil)
    NotificationCenter.default.removeObserver(self, name: UIResponder.keyboardWillHideNotification, object: nil)
}

@objc func keyboardDidShow(with notification: Notification) {
    guard let userInfo = notification.userInfo as? [String: AnyObject],
        let keyboardFrame = (userInfo[UIResponder.keyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue
        else { return }

    var contentInset = self.tableView.contentInset
    contentInset.bottom += keyboardFrame.height

    tableView.contentInset = contentInset
    tableView.scrollIndicatorInsets = contentInset
}

@objc func keyboardWillHide(with notification: Notification) {
    guard let userInfo = notification.userInfo as? [String: AnyObject],
        let keyboardFrame = (userInfo[UIResponder.keyboardFrameBeginUserInfoKey] as? NSValue)?.cgRectValue
        else { return }

    var contentInset = self.tableView.contentInset
    contentInset.bottom -= keyboardFrame.height

    tableView.contentInset = contentInset
    tableView.scrollIndicatorInsets = contentInset
}
