How can I make a Swift enum with UIColor value?

Question

I\'m making a drawing app and I would like to refer to my colors through use of an enum. For example, it would be cleaner and more convenient to use Colors.RedColor

Answer 1

I do it like this (basically using a struct as a namespace):

extension UIColor {
  struct MyTheme {
    static var firstColor: UIColor  { return UIColor(red: 1, green: 0, blue: 0, alpha: 1) }
    static var secondColor: UIColor { return UIColor(red: 0, green: 1, blue: 0, alpha: 1) }
  }
}

And you use it like:

UIColor.MyTheme.firstColor

So you can have a red color inside your custom theme.
