Appearance proxies / UI_APPEARANCE_SELECTOR in Swift?

Question

The Apple documentation states:

To participate in the appearance proxy API, tag your appearance property selectors in your header with UI_APPEARANCE

Answer 1

I did not find the solution but a workaround. Instead of annotating the properties I made them as a class variable.

private struct StarFillColor { static var _color = UIColor.blackColor() }
internal class var starFillColor: UIColor {
    get { return StarFillColor._color }
    set { StarFillColor._color = newValue }
}

And in the file where I setup all my appearances:

MyClass.starFillColor = UIColor.r(181, g: 60, b: 109) 

I hope it will help somebody!
