my answer is not correct

Hi I have a questions regarding my solution, I already test this code in playground and it actually worked. I also check the result in the asked is already the same with my playground, but why when i submitted it doesnt go through

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


let color = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
color.description

Hey Reagen,

your code is actually perfectly fine, good job! The only problem is that challenges are really picky and want you to do exactly what they say. In this case you have to take care to add a space after the colons before you interpolate the colors in the description and after the following commas. If you fix this, it should work!

Like so:

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

I hope that helps! :)
