Works in playground but not here

I used this code in playground and I was able to call the text, but it won't work here. Why?

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

enum Text {
    case Headline
    var headlineStyle: String{
        return "UIFontTextStyleHeadline"
    }
    case Body
    var bodyStyle: String{
        return "UIFontTextStyleBody"
    }
    case Footnote
    var footNoteStyle: String{
        return "UIFontTextStyleFootnote"    }


}

I had a lot of trouble with this one too. Because it's an enum, they want you to use a switch statement for the different cases. You also need a computed property named style specifically.

I don't know if I should post the answer here or not but let me know if you're still stuck.

Edit: Hey Team Treehouse, we were confused because this question is in the the wrong place. The video that explains how to do this is right after the question.

Brian, nice try, but you have 3 vars, none of which is style. This was tricky, as the previous videos never mention computed properties in enums.

Try this:

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 
     }
  }
}
