I don't get why this code won't pass?

I tried it in x-code and it worked fine which just makes me even more confused.

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)"

Hi Luke,

You're simply missing the commas after green, blue and alpha in your description string, see the below.

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

Happy coding!
