Treehouse TeacherYou're close except that your description should be set to a string Then we create an instance of the RGBColor and assign it to a constant and pass it the values we want the color to have. Take a look at my code.
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)"
}
}
let myColor = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
myColor.description
You do not have to write the last two lines. Your code will pass with them or without them. I included them to illustrate a point.
