I'm attempting to create a calculated property on an enum

I'm not sure how to tell which value the Text enum is to return the correct text.

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

enum Text {
  case headline
  case body
  case footnote

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

    }
  }
}

Instead of switching on Text (which is just the name of enum), switch on self: the actual reference of the current enum instance.

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

enum Text {
  case headline
  case body
  case footnote

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