Tuple Value Names

I attempted to assign price and carpet color to the tuple return values. It brings an error every time, not sure if this is because of an update in the language recently. But Xcode 7.2.1 does not allow(in my case) to use a name as an index value for tuples.

Try the code below.

func areaOfRoom1(length l: Int, width w: Int) -> Int {

    let areaRoom1 = l * w
    return areaRoom1
}





func carpetAreaCostCalculator
    (length length: Int, width: Int, carpetColor: String = "Tan") -> (price: Int,carpetColor: String) {


    let area = areaOfRoom1(length: length, width: width)
    var price: Int
    switch carpetColor {
    case "Tan": price = area * 1
    case "White": price = area * 2
    case "Blue": price = area * 4
    default: price = 0
    }

    return (price,carpetColor)

}

let carpetCost = carpetAreaCostCalculator(length: 10 , width:20 , carpetColor: "Blue")
let carpetCost1 = carpetAreaCostCalculator(length: 10, width: 20)

print ("The cost of the \(carpetCost.1) carpet is \(carpetCost.0)")```
