get this error

Don't use the memberwise initializer Swift creates. Add your own custom initializer as specified in the directions

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

    }
}

You need to remove the description parameter from the first line of your init method. You don't need it since the function call is already passing the necessary arguments to generate the description string (which you already correctly have in the body of the init method).

init(red: Double, green: Double, blue: Double, alpha: Double) {

Just fix this line and your code will pass.
