access UIView subclass properties in the Gesture recognizer handling method (SWIFT)

in Swift, i am adding gesture recognizers to some elements of my own subclass of UIView. In the recognizer handling method, I can access recognizer.view.

How can I cast this as my own UIView subclass, so that I can access its custom properties from within this method?

you could use something like this inside the handler

let myView: MyViewSubclass = recognizer.view as MyViewSubclass
myView.customProperty = "blah blah blah"
