UIStoryboardSegue Subclass identify Kind of segue

Question

class CustomSegue: UIStoryboardSegue {

    override init(identifier: String?, source: UIViewController, destination: UIViewController) {
        super.init(identifier: identifier, source: source, destination: destination)
    }

    override func perform() {

        self.source.navigationController?.pushViewController(self.destination, animated: true)

    }

}

In the above code, I am overriding the behavior of segue. It should use pushViewController only if the kind is Show (e.g.: Push) for other type it should perform the default behavior that It can.

How do I find the Kind of segue in the subclass perform() method?

i.e

       override func perform() {

            if kind==Push { 
              self.source.navigationController?.pushViewController(self.destination, animated: true)
            } else {
              super.perform()
            }

        }

In storyboard, select segue as custom segue and select kind as custom segue, for default behavior just select show segue (e.g. push)
