Bummer! Make sure you're adding a stored property to your subclass as specified in the directions

OK, it's again me :) so could you help me and tell me what wrong I do now. I stored property blueColor to the class ViewController, and gave it default value UIColor.blueColor(). "Preview" doesn't show any errors. So why can't I pass that challenge?

For any help, thanks in advance. Best Regards

colors.swift 
class ViewController: UIViewController {
    var blueColor: UIColor = UIColor.blueColor()

    override func viewDidLoad() {
        // Do any additional setup after loading the view, typically from a nib.
    }

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

Wow! I can't believe they would do something like this! You work is fine. The editor is just insisting on a constant rather than a variable (without any hint to that effect):

let blueColor = UIColor.blueColor()

the same error

sometimes it's quite annoying when you are coding in Xcode and everything is alright but when paste in to website field it doesn't work.

// this works!
let blueColor = UIColor.blueColor()

is the correct answer, which threw me off as well -- although the error doesn't say it, the instructor must be looking for the constant (let) version of a stored property rather than the variable (var) version:

// doesn't pass the check
var blueColor = UIColor.blueColor()
