2,769 PointsAssigning Double to the a string
I don't understand how to assign the doubles as as they ask to the string description?
struct RGBColor {
let red: Double
let green: Double
let blue: Double
let alpha: Double
let description: String
// Add your code below
init(red: Double, green: Double, blue: Double, alpha: Double, description: Double) {
self.red = red
self.green = green
self.blue = blue
self.alpha = alpha
self.description = "red:\(red), green:\(green), blue:\(blue), alpha:\(alpha)"
}
}

Two little things wrong there - not much!
You don't need to pass in description
into the init
method; you construct it inside init
.
Second, you want a space after each colon in your string to make it match the required output:
init(red: Double, green: Double, blue: Double, alpha: Double) { // <- don't pass in 'description'
self.red = red
self.green = green
self.blue = blue
self.alpha = alpha
// add space after each :
self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
I hope that helps,
Steve.
