Not really sure how to approach this one :/

I'm not sure what to do on this code challenge. Can somebody help explain how I can go about solving this one?

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

enum Text {
  case Headline
  case Body
  case Footnote
}

var style {

}

Here is the answer:

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
        }
    }
}

you need to create a computed property and calculate its value based on the value of "self".
