That looks mainly fine, bar some spacing issues in your string - there's a few issues, though:
The description
assignment needs to be inside your init
method, so move the closing braces to after that.
You want to have the self
keyword before the stored property name, like: self.red = red
.
You need to put types on your parameters; they are all of type Double
.
That all looks like:
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)"
}

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)"
}
}
