How do I do this?

My attempts are below...

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

    let description: String

    // Add your code below
    let colours = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0) // Attempt #1
    init(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0) // Attempt #2
}

So the question isn't asking you to actually input the values, but create an init method that would properly handle : given the values 86.0 for red, 191.0 for green, 131.0 for blue and 1.0 for alpha.

For example if I wanted an init method for a car that would take a top speed and a color my code would look like this:

struct Car {
    let color: String
    let topSpeed: Double
    let description: String

    init(color: String, topSpeed: Double) {   \\Description is computed and doesn't need to be here
        self.color = color
        self.topSpeed = Speed
        self.description = "Color: \(self.color), Top Speed: \(self.topSpeed)"
    }
}
