iOS Development Techdegree Student 8,296 PointsHello Can Some one tell me what is wrong with my code!
In the editor, I’ve declared a struct named RGBColor that models a color object in the RGB space.
Your task is to write a custom initializer method for the object. Using the initializer assign values to the first four properties. Using the values assigned to those properties create a value for the description property that is a string representation of the color object.
For example, given the values 86.0 for red, 191.0 for green, 131.0 for blue and 1.0 for alpha, each of the stored properties should hold these values and the description property should look like this:
"red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0"
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 description = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
