What is wrong?

Have I misinterpreted the question, or why does the compiler want a "declaration" at description, if I move it outside the init()?

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

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

}

You need to add the arguments in the initialization and you do not need the values when initializing

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)")
    }
}
