Hi
Is it possible to use an enum inside a tuple when returning something inside a function
here is my code I'm getting the error -- Cannot convert return expression of type 'CarpetColors.Type to return type 'CarpetColors'
What am I doing Wrong?
Thank You
func cost(length: Int, width: Int) -> Int { let area = length * width
return area
}
enum CarpetColors { case Grey case Tan case }
func carpetCostCalculator(length length: Int, width: Int, carpetColor: CarpetColors = .Tan) -> (Int, CarpetColors) {
// Grey Carpet = £1 sqft
// Tan carpet = £2 sqft
// deep Blue Carpet = £4 sqft
let area = cost(length, width: width)
var price: Int
switch carpetColor {
case.Grey: price = area * 1
case.Tan: price = area * 2
case.Blue: price = area * 4
}
return (price, CarpetColors)
}

There are two errors in the code above:
1- You missed the last case of enum CarpetColors , you should add the Blue option
2- The return statement should return the variable carpetColor not the enum type CarpetColors so it should be : return (price, carpetColor)
