How to do?

I defined an Init method but the compiler says "make sure it is not the memberwise one." I don't know how to solve this problem ,, appreciate your comments.

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: Double , green: Double , blue: Double , alpha: Double , description: string)
  {
  self.red = 86.0
  self.green = 191.0
  self.blue = 131.0
  self.alpha = 1.0
  self.description = "red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0"
  }
}

You don't need description in your initialization

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)")
    }
}
