AssociatedValues allows you to easily add stored properties in class extensions:

extension UIView {
  var identifier: String {
      get {
          return getAssociatedValue(key: "identifier", object: self, initialValue: "Unknown")
      }
      set {
          set(associatedValue: newValue, key: "identifier", object: self)
      }
  }
}

Enjoy!
