1,895 PointsI'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.
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
}
}
}

18,473 PointsInstead 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
}
}
}
