Can you anyone solve that?

I can't do that. I spent a few times to solve problem but I don't build the solution of like "Text.Headline.style".

Best Regards.

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

enum Text {
  case Headline
  case Body
  case Footnote
}

Hi again,

After type this question, I've tried again and found the solution just 8 minutes later. I love programming for this reason :]

''' <p>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

    }
}

}</p> '''

Hey Yigit,

That's my solution.

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
    }
  }
}

I also took a time to figure it out. But as you see you have just to switch 'self' and return the correct String.

Hope this helps =)
