iOS Object-Oriented Swift 2.0 Complex Data Structures Custom Initializers

I am having difficulty with this problem. I feel as if i've typed it correctly and i'm not getting any Errors in XCode

I do not understand the question. Do I have to input the given values? Also I'm not sure if my code will post with this automatically as it is my first time asking a question.

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, description: String){
        self.red = red
        self.green = green
        self.blue = blue
        self.alpha = alpha
        self.description = description
    }

}

This challenge is not asking you to add a description parameter to your initializer, but rather to build and assign a String for description inside your initializer. This worked for me:

init(red: Double, green: Double, blue: Double, alpha: Double){
      self.red = red
      self.green = green
      self.blue = blue
      self.alpha = alpha
      //Notice how I'm building the description from the other parameters, and not just taking it as an argument to the initializer
      self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
