8,429 PointsComputed properties and switch statements
So just worked through the computed properties section of the first course on Intermediate Swift.
I have one question about switch statements inside of a computed property.
When I add a switch statement to a computed property (example below)
let UIFontTextStyleHeadline = "UIFontTextStyleHeadline"
let UIFontTextStyleBody = "UIFontTextStyleBody"
let UIFontTextStyleFootnote = "UIFontTextStyleFootnote"
enum Text {
case headline
case body
case footnote
case style
var style: String {
switch self {
case .headline: return UIFontTextStyleHeadline
case .body: return UIFontTextStyleBody
case .footnote: return UIFontTextStyleFootnote
}
}
}
The compiler tells me that the switch statement isn't exhaustive.
However, looking at the video that follows the above code challenge, Prasan uses switch statements inside of computed properties, that are not exhaustive
Could somebody please explain this to me?

All the enum cases need to be used in the switch statement. My mistake was adding a case called style into the enum! Removing this satisfies the switch statements exhaustive clause and the code compiled.
