The compiler doesn't show any errors. Still it's a 'Bummer'. Can you check why?

Please check the code and help me understand what am I doing wrong

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 = 86.0
  green = 191.0
  blue = 131.0
  alpha = 1.0
  description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
  }
}

Hello mate. Your initializer was not set properly. This whey you can't set new values for the colors when you create a new instance. You should do like this:

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

    let description: String

    // Add your code below

    init(red: Double = 10, green: Double = 5, blue: Double = 6, alpha: Double = 2){
        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)"
    }

}
