How to write this one?

I can't figure out how the website wants me to write because the code am using is working in playground but not on the website

structs.swift 
struct RGBColor {
    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double
    let description: String

    init (red: Double, green: Double, blue: Double, alpha: Double) {
        self.red = red
        self.green = green
        self.blue = blue
        self.alpha = alpha
        self.description = ("red: \(red),green: \(green), blue: \(blue), alpha: \(alpha)")
    }

   description = ("")
}

You can eliminate your description call from your code; it does not ask for it

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
        self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
    }
}
