Code doesn't compile

I'm getting error even though I did what exactly is being asked. Can anybody help me with this please?

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

    let description: String

    // Add your code below
    init(r: Double, g: Double, b: Double, a: Double) {
        self.red = r
        self.green = g
        self.blue = b
        self.alpha = a

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

    }
}

Hi there,

I have come across this before and I agree that your code is correct. However, the challenge doesn't like the names of individual letters. If you change r to red etc. your code will compile.

I have flagged this with support before and got an answer that "it's just the way it is". I don't understand the technicalities of the tests behind the scenes.

So, change your r to red in both places (and for the others too) and your code will compile.

Steve.
