You do not need to assign value when initializing. Also you need initialize description inside init

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) {

    self.red = red
    self.green = green
    self.blue = blue
    self.alpha = alpha
    self.description = ("red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)")

  }
}
