Another poor question - I can't understand from the compiler errors what I am doing wrong - swift 2.0 changing

Let's get some practice working with views and colors! In the editor below you have a view controller subclass.

Add a stored property to the view controller named blueColor and assign an instance of UIColor as the default value.

You can use UIColor's RGB initializer method and pass the values 0,0,255,1.0 for red, green, blue and alpha respectively. Alternatively, UIColor has a convenience method that you can use: UIColor.blueColor().

This is my answer, I have tried several different ones

class ViewController: UIController { /* declaring the stored property with an Instance of UIColor as the default value using the convenience method */ let blueColor = 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
}

}

I then get this error

swift_lint.swift:48:23: error: use of undeclared type 'UIController' class ViewController: UIController { ^~~~~~~~~~~~ swift_lint.swift:52:19: error: method does not override any method from its superclass override func viewDidLoad() { ~~~~~~~~ ^ swift_lint.swift:56:19: error: method does not override any method from its superclass override func didReceiveMemoryWarning() {

Any idea why Treehouse can become so frustrating / what is the solution to this problem?

class ViewController: UIController {

    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
    }

    let blueColor = UIColor()
    view.backgroundColor = blueColor(red: 0, green: 0, blue: 255, alpha: 1.0)
}
