RGB Initializer

Forgive me if this is a silly question, but after watching and re-watching the video I don't understand how I'm supposed to be making a custom initializer for this challenge.

I've tried putting the sample values into the parameters, I've tried using "self.red, etc." but neither 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) {
      red = 86.0
      green = 191.0
      blue = 131.0
      alpha = 1.0
    }
}

I ended up figuring it out!

Here's my completed code. I'll comment it out if people would like:

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

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