How to update the text of a UILabel when the user fill in some Text Fields

I need to update a Label with the text the user has typed in some Text Field on the same Screen. If possible I'd prefer to update it as the user types.

yes it is possible if you are using interface builder make a new @IBAction from your textField like in the image image and choose Editing Did Change

  @IBAction func tfUpdate(_ sender: UITextField) {
        label.text = sender.text
    }

You can listen to the textfield changes by adding a target for event UIControl.Event.editingChanged and update your label in the selector function. You can add target to the text field as follows.

textField.addTarget(self, action: #selector(textFieldDidChange(_:)), for: .editingChanged)

And in the objc function, you can update the label content.

@objc func textFieldDidChange(_ textField: UITextField) {
        label.text = textField.text
    }
