I can't understand what the task is about
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 = red
self.green = green
self.blue = blue
self.alpha = alpha
}
}

Courses Plus Student 15,510 PointsHi Johnny Nguyen,
You're so close!! Just misreading the challenge on one part (had to do the challenge myself to confirm that!)
Your task is to write a custom initializer method for the object. Using the initializer assign values to the first four properties.
You basically nailed this part, but added a 5th property - description.
// Challenge: first four (4) properties (r/g/b/a). Got to remove that description
init (red: Double, green: Double, blue: Double, alpha: Double, description: String) {
self.red = red
self.green = green
self.blue = blue
self.alpha = alpha
}
Next part of the challenge
Using the values assigned to those properties create a value for the description property that is a string representation of the color object. ... description property should look like this: "red: 86.0, green: 191.0, blue: 131.0, alpha: 1.0"
Let's use some string interpolation and build it to the specs of the example given
self.description = "red: \(red), green: \(green), blue: \(blue), alpha: \(alpha)"
Pop that into your initializer method and you should be laughing.
Hope this helps you out mate.
Great effort! and keep on coding
Dave
