This sections is HARD!

  let description: String

  // Add your code below
  init {
      self.red = 86.0
      self.green = 191.0
      self.blue = 131.0

You are very close! The challenge is not expecting you to hardcode the values but rather it is an example of what the outcome would be if the object was initalized:

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)"
  }
}

In addition, you only created an init{} object rather than an init function.
