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
// 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: \(self.red), green \(self.green), blue: \(self.blue), alpha: \(self.alpha)"
}
}

It's just a little typo... You are missing a colon after "green" in this line:
self.description = "red: \(self.red), green \(self.green), blue: \(self.blue), alpha: \(self.alpha)"
Just add that and everything else looks good! :)
Keep Coding!
