I recommend going back through the videos on it seems you are confusing methods with initialization. You need to create a custom initializer:

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)")

  }
}
