I don't understand the hint Make sure you are using a member-wise initializer. I don't see where the error is.

I don't see where I made the mistake. Thanks for the hint if you please.

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

  let description: String

  // Add your code below
  /* Custome initializer method */
  init(red:Double, green:Double, blue:Double, alpha:Double, description:String){
    self.red = red
    self.green = green
    self.blue = blue
    self.alpha = alpha
    // Use string interpolation in Swift
    self.description = "red:\(red), green:\(green), blue:\(blue), alpha: \(alpha)"
  }
}

The instructions are: Using the initializer assign values to the first four properties. You don't need to pass in a description because it will be created with those four properties.
