Can you show me the correct code. I've tried various codes and cannot solve.
Thank you very much!
John
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)
{
self.red = red
self.green = green
self.blue = blue
self.alpha = alpha
description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}

You pretty much have it! There is just a small syntax error when you declare the description
variable in the Struct
. You have used the equal sign instead of a colon. Doing this, the compiler thinks String
is trying to be assigned to the variable, which is causing the syntax error. Just fix that up and you're good to go. :)
Keep Coding! :)
