11,948 PointsCustom initializer method in swift.
Why do I keep getting the error message to create my own custom initializer in the test? Isn't it what I'm doing?
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, description: String) {
self.red = r
self.green = g
self.blue = b
self.alpha = a
self.description = "red: \(r), green: \(g), blue: \(b), alpha \(a)"
}
}

37,115 PointsAs you don't use the description parameter for creating a value for the description property, it is not necessary to declare it within the list of initializer parameters. The signature of the initializer should probably look like this:
init(r: Double, g: Double, b: Double, a: Double) {
// Your initialization code goes here...
}
