added values to RGBColor still not working

structs.swift
struct RGBColor {
  let red: 86.0
  let green: 191.0
  let blue: 131.0
  let alpha: 1.0
}
  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

For this challenge what it wants you to do is to create an initializer for the struct

The first mistake in the code above is that the property "description" and your init method should be inside the struct.

Secondly, you don't need to initialize the stored properties to actual values, leave it as uninitialized Doubles. This is the purpose of the init method.

Other than that, everything else looks perfect! Best of luck =)

*By the way, if you wanted to initialize your stored properties it would look like " let alpha: Double = 1.0" or "let alpha = 1.0"
