struct initializationRGBColor

How to solve struct initializationRGBColor problem

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

let aColor = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
aColor.description

I changed description = ("red:(red),green:(green),blue:(blue),alpha:(alpha)") to self.description = ("red:(red),green:(green),blue:(blue),alpha:(alpha)"). It is working in playground but not in online compiler

In directly coping the code supplied above, there is an issue with not having a closing bracket for the struct, so check for that which might help.

// You have:
struct RGBColor {
    init(...) {
    }

// Should have:
struct RGBColor {
    init(...) {
    }
} // <- missing closing bracket

Secondly, the issue you may run into is that the Treehouse compiler is probably looking for a direct match of the string, so place a space after each color i.e.

description = "red: \(red) ..." // etc
