iOS Object-Oriented Swift Complex Data Structures Custom Initializers

How should I construct my description property?

The Hint is telling me to use string interplotation which I'm already using. Can someone explain where the real mistake is?

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){
    self.red = red
    self.green = green
    self.blue = blue
    self.alpha = alpha
  }

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

The description string interpolation should be inside the init method and “marked” with self. Aside form that it’s correct.
