Hi, you have to create a computed property separated from the enum's cases, but still inside the enumeration. Inside the computed property named style you have to do a control flow to associate the cases to the styles provided by the constants. I chose a switch statement, because it fits perfectly with an enum.

Here is how I did it. Hope I could help you understand a little better:

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

enum Text {
    case headline
    case body
    case footnote

    var style: String {
        switch self {
        case .body: return UIFontTextStyleBody
        case .footnote: return UIFontTextStyleFootnote
        case .headline: return UIFontTextStyleHeadline
        }
    }
}
