What do I miss ?

Hello Can I know why my answer is not accepted?

colors.swift 
class ViewController: UIViewController {

    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
        let blueColor = UIColor(red: 233/255.0, green: 86/255.0, blue: 94/255.0, alpha: 1.0)
            view.backgroundColor = blueColor


    }

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

Hey Haytham Alam,

You need to be using the exact blue color that they provide in the instructions of the challenge. This challenge is extremely picky on how you format the instantiation of the UIColor. Therefore, I recommend using the convenience initializer for UIColor.

class ViewController: UIViewController {

let blueColor = 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
    }
}

If you are determined to use the UIColor RGB initializer, maybe try one of these solutions:

let blueColor = UIColor(red: 0, green: 0, blue: 1.0, alpha: 1.0)
let blueColor = UIColor(red: 0, green: 0, blue: 255/255.0, alpha: 1.0)

Good Luck!
