iOS Object-Oriented Swift Complex Data Structures Custom Initializers

My code cannot be compiled

I have a code for this task. Compiler on website give me the message that my code cannot be compiled and my Xcode is frozen and don't show anything.

struct RGBColor {
    let r: Double
    let g: Double
    let b: Double
    let alpha: Double
    let description: String
    init(r: Double, g: Double, b: Double, alpha: Double, description: String ) {
        self.r = 86.0
        self.g = 191.0
        self.b = 131.0
        self.alpha = 1.0
        self.description = "\(self.r), \(self.g), \(self.b), \(self.alpha)"

The challenge is asking for a very specific answer. The code may work in a playground without error, but in order for the challenge to pass you must provide everything that is asked. However, in your case here, there are a few significant errors that wouldn't pass In either case. For one, inside of your initializer method, you have assigned values to the color properties, which does not make sense to do if the whole point Is to use a struct and an initializer. Second, you haven't followed the correct naming scheme as the code challenge is stated.

// Object Oriented Swift -> Complex Data Structures -> CUSTOM INITIALIZERS

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)"
