2,070 PointsInitializer final question - why isnt this working??
I think I have done everything correctly in this test and I keep on getting make sure you are not using the member wise ...
What is wrong with my code?
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 = 86.0
self.green = 191.0
self.blue = 131.0
self.alpha = 1.0
self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
}
}

8,386 PointsHi Gustavo,
Two things: 1) Don't include description as an init parameter 2) Don't hardcode the color values in the init method. Instead you will assign the parameter values to the corresponding struct properties (the color variables).
Here's the 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)"
}
}
Now if you want to create a RGBColor object (and print to see the description string), you can do this in Playgrounds:
let myRGBColor = RGBColor(red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0)
print(myRGBColor.description)
