title: How can I make a Swift enum with UIColor value?
body: <p>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 <code>Colors.RedColor</code> instead of typing out values every time I want that red color. However, Swift's raw value enums don't seem to accept UIColor as a type. Is there a way to do this with an enum or something similar?</p>
