iOS Object-Oriented Swift Complex Data Structures Custom Initializers

structs.swift test does not accept my code for the RGBColor structure, but online playground does. What should I do?

The TreeHouse "Recheck work" button tells me to make sure I am not using the memberwise initializer. I thought my init statement was pretty clear.
The last two lines of the code were my tests in the online playground to prove it worked...

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

} 
let myRGBColor = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0, description: "")
print(myRGBColor.description)

Just remove description from the init method and it should work:

   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)"
    }
