Custom Initializers " Bummer! The value of description does not match with the directions specified"

To my eye and understanding of the instructions, this is identical to what others say has worked to get them through this challenge.

It doesn't send up any alerts in a Playground, but gets the "Bummer! The value of description does not match with the directions specified" reaction from the challenge.

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)")
    }
}

Nancy, it's fussing because it wants a space between the labels and the values. You have:

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

It wants:

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

Thanks, jcorum. You saved me again. I didn't know white space was that crucial. Learning. Thank you.
