stuck on coding challenge

I can't figure out how to compute properties with enum cases

enum.swift 
let UIFontTextStyleHeadline = "UIFontTextStyleHeadline"
let UIFontTextStyleBody = "UIFontTextStyleBody"
let UIFontTextStyleFootnote = "UIFontTextStyleFootnote"

enum Text {
  case Headline
  case Body
  case Footnote
}

this is a tricky one at first. It should look like this..

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 
    }
  }
}
