What exactly is wrong with the following code to create a custom initializer in Swift?

The instructions dictate to create a custom initializer for the properties within the struct RGBcolor and then create values for the 4 properties and then finally create a string representation for the properties. I feel like I did that, the compiler is returning no errors, and I am having issues with this because I want to move on but I don't want to continue if I don't know what I'm doing

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

    let description: String

    // Add your code below
}

This should get you through, rewatch the last video and you should get it. If not, keep asking ;)

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)"
    }
}
