Computed Properties

I'm confused with this code challenge

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

enum Text {
  case headline
  case body
  case footnote
}
var style: Text

Hint: "var style" is supposed to be inside of this enum and of type "String" because from "Text.headline.style" we can tell that "style" cannot be outside of Text's scope.

enum Text {
  case headline
  case body
  case footnote

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