Scroll UITextField above Keyboard in a UITableViewCell on a regular UIViewController

Question

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

In swift4 we can create an extension of UIViewController.

extension UIViewController {
    //MARK: Keyboard user interactions
    func handleContainerViewFrameOnKeyboardShowHide(originalContainerFrame: CGRect) {
        NotificationCenter.default.addObserver(forName: NSNotification.Name.UIKeyboardWillShow, object: nil, queue: OperationQueue.main) {(notification) in
            var info = (notification as NSNotification).userInfo!
            let keyboardFrame: CGRect = (info[UIKeyboardFrameEndUserInfoKey] as! NSValue).cgRectValue
            var tableViewFrame = originalContainerFrame
            tableViewFrame.size.height = originalContainerFrame.size.height - keyboardFrame.size.height
            self.view.frame = tableViewFrame
        }
        NotificationCenter.default.addObserver(forName: NSNotification.Name.UIKeyboardWillHide, object: nil, queue: OperationQueue.main) { (notification) in
            self.view.frame = originalContainerFrame
        }
    }
}
