Hope the code below helps in understanding.
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
self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}
let newColor = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
newColor.description

2,151 PointsYou don't need to initialize 'description' in the initializer method because it's value is definite. Initializer is used only for those variables and constants whose value is determined while creating and instance which isn't the case with 'description' Assign the value to 'description' out of the init method and you're good to go! Hope it helps
