are we able to init part of the struct or should we make it all ?

I have tried first to do only init to the Double without the String but it didn't go through and after I put the string it is not making errors but it is still not working I just need help

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

  let description: String
  init(red: Double, green: Double, blue: Double, alpha: Double, description: String){
        self.red = red
        self.green = green
        self.blue = blue
        self.alpha = alpha
        self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"

    }
    func colors() -> [RGBColor] {
        let results = [RGBColor]()


        return results
    }
}

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

Hi Jeremy Conley , your answer is correct however it is better to put your answer in the answer pane in the bottom of this page instead of a comment. In that way the user can mark your answer correct.

You don't need a description parameter, you set it based on the color values you passed through

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)"
  }
}
