Works in xCode but I get compilation error on objective

Not sure what the deal is. Tried in Chrome and Safari.

structs.swift 
struct RGBColor {
    let red: Double
    let green: Double
    let blue: Double
    let alpha: Double

    let description: String

    init () {
        self.red = 1.00
        self.green = 2.00
        self.blue = 1.00
        self.alpha = 1.00
        self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
    }
}

Hey Jesse,

So what you currently have will compile perfectly fine, although it's not quite right to satisfy the requirements of the challenge.

Currently, inside your init method we are assigning hard coded values to your variables. You want to change your init method to accept four parameters that will be used to populate your variables with data.

init(red: Double, green: Double, ...)
{
    self.red = red
    self.green = green
    ...
    ...
}

This is the sort of thing you need, though you'll need to your blue and alpha values in there too. Hope this sets you on the right track!
