could you be more specific?

could you be more specific? I don't understand clearly the test

structs.swift 
struct RGBColor {
    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double

    let description: String

    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
    }

     func colorAssiged() -> String {

        let result  = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha) "


    return result


    }



    // Add your code below
}

let callingRGBColor = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0, description: "gato")

callingRGBColor.colorAssiged()

Thanks I have corrected like this:, but It doesn't work, it says check the preview , and its in blank. In my playground is ok. Could you please help?

struct RGBColor { let red: Double let green: Double let blue: Double let alpha: Double

let description: String

 // Add your code below
  init(){
  red = 86.0 
  green = 191.0
  blue = 131.0
  alpha = 1.0
  description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}

so close... this works. But, make sure to read through the above thread as to why self is necessary

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)"
  }
}
