Accessing the view controller's backing view from Build a Simple iPhone App with Swift 2.0 (Challenge 2/2)

Can't figure out why this won't work. :(

colors.swift
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
    }
}

Hello Jeff! I'm no expert myself, but I think I got this one figured out. You are accessing the instance of UIColor correctly inside the viewDidLoad function. But you are in this line "let blueColor = UIColor.blueColor()" trying to access itself. You need to set a constant with the NAME blueColor as an INSTANCE of UIColor. Do you se the difference between what I did, and what you had? :)

Hope this helps, cheers and good luck

class ViewController: UIViewController {
    let blueColor = UIColor(red: 0, green: 0, blue: 255, alpha: 1.0)

    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
    }
}
