Task is not clear !

The task requirement is not clear:

  • is the required property a standalone one or part of a struct ?

I have created code below a try to solve it, it works in xcode but not here:

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

enum Text {
    case Headline
    case Body
    case Footnote
}

var x: Text
x = Text.Body

var style: String {
    switch x {
    case .Headline: return UIFontTextStyleHeadline
    case .Body: return UIFontTextStyleBody
    case .Footnote: UIFontTextStyleFootnote
    }
    return ""
}

I found the answer is the following video:

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
}
}

}
