In the editor, I’ve declared a struct named RGBColor that models a color object in the RGB space. Your task

In the editor, I’ve declared a struct named RGBColor that models a color object in the RGB space.

Your task is to write a custom initializer method for the object. Using the initializer assign values to the first four properties. Using the values assigned to those properties create a value for the description property that is a string representation of the color object.

For example, given the values 86.0 for red, 191.0 for green, 131.0 for blue and 1.0 for alpha, each of the stored properties should hold these values and the description property should look like this:

"red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0"

Note: Init methods typically list parameters in the same order of property declaration. For this task, stick to the order red,green,blue,alpha.

What am I doing wrong?

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