RGB Struct generates solution in playground but not in the challenge

The following doesn't solve the challege

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

Same goes if you pass the parameters as opposed to the newly assigned self.property.

In the Xcode playground, the code does render and an instance returns the description, however the challenge tells me to check I am passing the correct description.

Maybe some fresh eyes would be better.

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

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

let RGB = RGBColor(red: 86.0, green: 191.0, blue: 131.3, alpha: 1.0)

Hello Dennis O'Keeffe, I am stuck in the same challenge my compiler it shows that everything is fine in my playground but once I import it to the challenge task does not work! =( This is my code

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

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)"

}

}

let color = RGBColor.init(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0) color.description
