Please help to check my code, why this code could not pass the code challenge ?

Question

struct RGBColor {
    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double

    let description: String

    // Add your code below

    init(red: Double = 86.0, green: Double = 191.0, blue: Double = 131.0, alpha: Double = 1.0, description: String = "red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0"){

        self.red = red
        self.green = green
        self.blue = blue
        self.alpha = alpha
        self.description = description

        }
}

Hey Jack,

There are just a few small errors in your code. To begin, I believe this challenge requires the use of String Interpolation for the description. This means that rather than initializing

self.description = description

you should instead initialize something along the lines of:

description = "red: \(red), green \(green)"

and so on for the remainder of the colors.

I would also refrain from placing the numerical values inside the initializer. Instead, call upon RGBColor in an instance, and then declare those values. It would look a little something like this:

let colors = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)

Hope this clears things up! Make those few changes and your code will be sure to pass the challenge!
