    let alpha: Double
    init (red: Double, green: Double, blue: Double, alpha: Double){
        self.red = 86.0
        self.green = 191.0

This one was a bit weird.

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)"
    }
}

need to write self.description in the init method and put it as a constant property of the struct in order to call this...

RGBColor.description

as specified in the challenge.
