Not sure what this challenge wants me to do. Swift

The 2nd part of the challenge...Not sure what it wants me to do.

colors.swift 
class ViewController: UIViewController {



    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
        let blueColor = UIColor(red: 0/255.0, green: 0/255.0, blue: 255/255.0, alpha: 1.0)
        view.backgroundColor = blueColor
    }

    override func didReceiveMemoryWarning() {
        // Dispose of any resources that can be recreated
    }

}

Real close. They just wanted you to add the blueColor property in the viewController and not in the viewDidLoad like this...

class ViewController: UIViewController {
    let blueColor: UIColor = UIColor.blueColor()
    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
        view.backgroundColor = blueColor 
    }

    override func didReceiveMemoryWarning() {
        // Dispose of any resources that can be recreated
    }
}

I modeled the blueColor property like this just because i felt it was easier
