1,430 PointsHow do I know if I'm using the Memberwise initializer method?
I have typed up what I believe to be the correct code, but the message it gives me to tell me I'm wrong is to "Make sure you're not using the default Memberwise Initializer method. I'm not sure how to know if I am or not.
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, description: String) {
self.red = 86.0;
self.green = 191.0;
self.blue = 131.0;
self.alpha = 1.0;
self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)";
}
}

Your spot on minus one thing. Remove description as part of your init inputs. You don't need a description input. Well done sir! Also set your initializers to themselves. You will initialize values for these when called.
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)";
}
}
Using your struct:
let tv = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
tv.description

1,430 PointsThank you! That was it! I was about to go crazy trying to figure that out.

7,511 PointsHey Ben, made one more change I think you should see! Oversight when I first looked at it.
