You need to use the switch statement within the enum to check all the possible variations.

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
    }
  }
}

Once you have all the cases, just return the pre-defined variables that are at the top.

Hope this helped! Don't forget to mark the answer if it did :)
