Misunderstanding the question

Anyone can help me to solve this exercise?

structs.swift 
struct RGBColor {
    var red: Double
    var green: Double
    var blue: Double
    var alpha: Double

    var description: String

    // Add your code below
    init() {
      red = 86.0
      green = 191.0
      blue = 131.0
      alpha = 1.0
    }
}

They want you to pass in the init arguments, set the properties on the struct to those arguments, and then set the description.

init(red: Double, green: Double, blue: Double, alpha: Double) {
  self.red = red
  self.green = green
  self.blue = blue
  self.alpha = alpha

  description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
