iOS Object-Oriented Swift Complex Data Structures Custom Initializers

Object-Oriented Swift 3 - Not using `self` to initialize.

Instead of using self to initialize each of the properties, I assigned a value directly with no parameters which I believe is a better coding. Home come the task didn't accept my work?

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)"
    }
}

let color = RGBColor()
let description = color.description

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)"
  }
}

You've forgot to put the values in the initializer. When you assign the values directly, the initializer has no sense.

@eberhapa Thanks for the feedback. I guess my question was more toward in finishing the assignment.
