I tried to declare the style property out side the enum .. it did not work

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

enum Text {
  case headline
  case body
  case footnote

  var style : String {
     switch Text {

        case .headline : return UIFontTextStyleHeadline

         case .body : return UIFontTextStyleBody

      case .foornote : return UIFontTextStyleFootnote

   }
  }
}

Change text to self and change your last case from foornote to footnote and you should be good homie.

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
    }
    }
}
