Need help with this

I don´t know what is wrong here...

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

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

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

}

}

You're super close! In the init method, assign the value of the stored property to the value of the argument.

init (red: Double, green: Double, blue: Double, alpha: Double) {
     self.red = red
     self.green = green
     self.blue = blue
     self.alpha = alpha

}

The description is super close. You've already declared it above the init. Don't interpolate there. Interpolate within the init method for this challenge.

//before the init
let description: String

//interpolate description within the init
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)"
}
