My code works just fine in playground, not sure why this isn't passing

Can't get this to pass the code challenge, but works just fine in playground.

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 = 86.0
        green = 191.0
        blue = 131.0
        alpha = 1.0

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

var x = RGBColor()

print(x.description)

Hey, the init isn't set up to initialise anything. Try understanding the differences between what you've got currently and the solution below, this should make it clear how to use inits :)

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: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"

} }
