You're doing good so far! You just need to finish with the self.description part of your init method. 

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

        // Here you need to create a string that complies to the request in the directions. 
        self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
    }

}
