Help please

Hey Max,

I also had a bit of trouble figuring this one out too, but it kinda made sense in the end, the challenges can be very particular with what they are looking for.

your first part setting up the Init method is almost right, however we dont have to assign any values to it. Think of this Init method as a blueprint for all other instances (copies) of the RGBColour struct. So inside this Init method we are assigning red to red, blue to blue etc so it should look like this:

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

Finally the part that confused me a little was adding in the description, i assumed it would have to be set up like

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

However this is not the case, my understanding is the concatenation of the description is set up inside the Init method however we do not have to specify it as a parameter (it is passed in via the struct?)

So my final code looked like this:

    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)"
    }

Hope this helps =]
