1,165 PointsNot sure how to call the init/struct?
So I think the instance method is correct, I just don't how to call the init to get it to display the numbers i want '86.0,', '131',0', etc.... I hope that makes sense?
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
description = "red:\(red), green:\(green), blue:\(blue), alpha:\(alpha)"
}
}
let colour = RGBColor.init(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)

22,160 PointsYou have done well. All you need to do is call the Class directly. The init method will be called automatically when your parameters you pass in match those asked for by the init method you have defined.
One other thing, you need spaces in your description string after the colons and before the interpolated values.
With these corrections your code looks like this.
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
description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}
let colour = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
Keep upt he great work! :)
