I have a problem with Computed Properties

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

enum Text {
  case Headline
  case Body
  case Footnote
}

var style: Text{

var style:String{

  switch (style).self {
  case Text.Headline:UIFontTextStyleHeadline
  case Text.Body:UIFontTextStyleBody
  case Text.Footnote:UIFontTextStyleFootnote

  }


}
}

Heres how you would do it

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"
  } 
}
}

They wanted you to put the var style inside the enum so you could call it like Text.Headline.style
