I can run this code in XCode playground but treehouse's IDE do not accept it. Can you explain what's wrong?

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

    let description: String

    init(red:Double = 86.0, green:Double = 191.0 ,blue:Double = 131.0 , alpha:Double = 1.0)
    {
        self.red = red
        self.green = green
        self.blue = blue
        self.alpha = alpha

        var redString = "red:" + String(self.red) + ", "
        var greenString = "green:" + String(self.green) + ", "
        var blueString = "blue:" + String(self.blue) + ", "
        var alphaString = "alpha" + String(self.alpha)

        self.description =  redString + greenString + blueString + alphaString

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

    let description: String

    init(red:Double = 86.0, green:Double = 191.0 ,blue:Double = 131.0 , alpha:Double = 1.0)
    {
        self.red = red
        self.green = green
        self.blue = blue
        self.alpha = alpha

        var redString = "red:" + String(self.red) + ", "
        var greenString = "green:" + String(self.green) + ", "
        var blueString = "blue:" + String(self.blue) + ", "
        var alphaString = "alpha" + String(self.alpha)

        self.description =  redString + greenString + blueString + alphaString

    }
}

This particular code was not being accepted despite functioning as intended. Any suggestions are welcome.

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

    let description: String

    // Add your code below
    init(red: Double = 86.0, green: Double = 191.0, blue: Double = 131.0, alpha: Double = 1.0, description: String) {
      self.red = red
      self.green = green
      self.blue = blue
      self.alpha = alpha

      var redString = "red: \(self.red), "
      var greenString = "green: \(self.green), "
      var blueString = "blue: \(self.blue), "
      var alphaString = "alpha: \(self.alpha)"

      self.description =  redString + greenString + blueString + alphaString

    }
}

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