iOS Intermediate Swift 2 Properties Computed Properties

Help on computed properties. I believe this is the correct answer.

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

enum Text {

case Headline
case Body
case Footnote

var style: String {

    get {
        return UIFontTextStyleHeadline
    }
}

}

Text.Headline.style

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

enum Text {

    case Headline
    case Body
    case Footnote

    var style: String {

        get {
            return UIFontTextStyleHeadline
        }
    }
}

Text.Headline.style

1 Answer

This is the correct answer:

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
        }
    }
} 

you need to switch on self and based on what value you have there you return the correct style
