could you be more specific? I don't understand clearly the test
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, description: String) {
self.red = red
self.green = green
self.blue = blue
self.alpha = alpha
self.description = description
}
func colorAssiged() -> String {
let result = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha) "
return result
}
// Add your code below
}
let callingRGBColor = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0, description: "gato")
callingRGBColor.colorAssiged()

2,580 PointsThanks I have corrected like this:, but It doesn't work, it says check the preview , and its in blank. In my playground is ok. Could you please help?
struct RGBColor { let red: Double let green: Double let blue: Double let alpha: Double
let description: String
// Add your code below
init(){
red = 86.0
green = 191.0
blue = 131.0
alpha = 1.0
description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}

47,353 Pointsso close... this works. But, make sure to read through the above thread as to why self is necessary
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)"
}
}
