3,536 PointsString interpolation in Structs not working!! Please help!
I just want some clarification on how structs and init work. And also I would like to know where I am going wrong.
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
}
// Add your code below
description = "red: \(self.red), green: \(self.green), blue: \(self.blue), alpha: \(self.alpha)"
}

23,970 PointsYou need to initialize description
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)")
}
}
