349 PointsI cannot figure this out, how do you do it?
Here is the code:
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
}
func RGB() -> String {
let description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
return description
}
}
let color = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
let description = color.RGB()
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
}
func RGB() -> String {
let description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
return description
}
}
let color = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
let description = color.RGB()

5,225 PointsThey want you to initialize description in the init() method, like so:
struct RGBColor {
let red: Double
let green: Double
let blue: Double
let alpha: Double
let description: String
init(red: Double, green: Double, blue: Double, alpha: Double) {
self.red = red
self.green = green
self.blue = blue
self.alpha = alpha
description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}
let color = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
let description = color.description

349 PointsGreat thank you, why do you add the description inside the init? That is the only thing I don't understand. And why don't you declare description inside the init(xxxxx)? Thank you
