How to solve this

I simply don't understand how to solve this. How you can use enums with computed properties?

Hello,

Computed properties are like methods, you can return value from its body. 

let UIFontTextStyleHeadline = "UIFontTextStyleHeadline"
let UIFontTextStyleBody = "UIFontTextStyleBody"
let UIFontTextStyleFootnote = "UIFontTextStyleFootnote"

enum Text {
  case headline
  case body
  case footnote

    var style: String {
        switch self {
        case .headline : return UIFontTextStyleHeadline
        case .body     : return UIFontTextStyleBody
        case .footnote : return UIFontTextStyleFootnote
        }
    }
}

Hope this helps !
