Swift Object Oriented Programming Task 1 of 1 with Initializing -- can't understand my error here

Can't understand why this solution does not pass -- seems to match successful solutions I've seen in other question threads but maybe I'm missing something. Error is of the "bummer" type, something about description not pertaining to what's layed out in the query? No errors listed when I preview.

structs.swift 
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)"
          } 
    }

You are missing a comma before alpha in the description, I think

That might be it - the Treehouse compiler is quite particular about your output exactly matching what it expects.

I can't see any difference between what I have written, and what you have written, but the below works for me. Possibly the spacing on the curly braces at the end of your code? I did get an error when using uppercase letters in my description, like "Red: (red), Green: \green)"...etc

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)"
    }
}
