What don't you understand about it? The below code should complete the challenge.

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)"
    }
}
