I have rewatched the videos in this course but I still have no clue how to do this task. I don't even know what Q to ask

I know this is not a question but I really don't know what I should do. I guess I don't know how to use the enum in a way that I can call up the style computed property. I wish there was some resources that I could be given on the task so that I wouldn't have to ask a question of this nature. Not sure how to even start.

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

enum Text {
  case Headline
  case Body
  case Footnote

    var style: String{

    }
}

You have made a good start. Here is a hint, try incorporating a switch statement into your style's computed property.

computed properties . keep the “var style” switch statement in the curly braces body of the ” enum text” so you can call it like this “Text.Headline.style”

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"
    }



}

}

Text.Headline.style
