I am stuck. It is telling me the value of description does not match with the directions specified.

I can't figure out what I am missing

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)

Hey Davis,

Your code is correct, it is just a spacing issue and you are missing one comma. Challenges are very picky when they ask you to return, print, etc something (especially a String).

You'll notice the self.description has spaces after the commas and after the colons. (And you are missing a comma before 'alpha'

Fix that and you're good! :)

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

Keep Coding!
