What's wrong with this?

Need help understanding what is wrong with my init

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

Hi there,

You have used forward slashes in your interpolation; change those to backslashes and your code looks about right! 

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

And you don't need to use self in the brackets; the above would work just as well but that's a matter of individual style, I guess.

Steve.
