3,526 PointsNot sure what went wrong
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, description: String){
self.red = 86.0
self.green = 191.0
self.blue = 131.0
self.alpha = 1.0
// self.red = red // self.green = green // self.blue = blue // self.alpha = alpha self.description = "red: (red), green: (green), blue: (blue), alpha: (alpha)" // self.description = description }
func describe() -> [RGBColor] {
let result = [RGBColor]()
return result
}
}
let stuff = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0, description: "")

6,204 Points- description should not be passed in as an argument to the initializer.
- The numbers are just an example. The bit in code is wrong, but the stuff you wrote underneath with the slashes is correct there.
- You can't initialize self.description twice.
- String interpolation uses a backslash followed by parenthesis: "string (notAString) string"
- I don't know where you got that func "describe" from, but it's not mentioned in the task.
This is my solution: Please only use it if you are really stumped
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 isn't necessary here because there is no constant for the compiler to confuse it with.
description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}
