How can I deal with @objc inference deprecation with #selector() in Swift 4?

Question

I\'m trying to convert my project\'s source code from Swift 3 to Swift 4. One warning Xcode is giving me is about my selectors.

For instance, I add a target to a butt

As of, I think Swift 4.2, all you need to do is to assign @IBAction to your method and you can avoid this silly @objc annotation

```

let tap  =  UITapGestureRecognizer(target: self, action: #selector(self.cancel))


@IBAction func cancel()
{
    self.dismiss(animated: true, completion: nil)
}
