I'm trying to solve it with view.backgroundColor

What am I doing wrong? Is view false?

class ViewController: UIViewController {

  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.
  var blueColor = UIColor.blue
  view.backgroundColor = blueColor

Hi Bruce,

You want to assign the background color to your view inside the viewDidLoad. Fix that and it'll pass :)
