The problem is that everything in the Quotations will be printed. Try this,

description =  "\(red), \(green), \(blue), \(alpha)"

This will make it so that it only prints the colors and the commas. Hope this Helps. Tell me if it dosen't

Actually never mind. I just read the code challenge. It says to use string Interpolation for the description. I will get back to you shortly

Okay I figured out the problem. Your code was correct but the description line should have been inside of the init function. So it should look like this. (This code will complete the code challenge. I checked. 🙂)

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)"
  }
}

Good Luck 😀
