iOS Build a Simple iPhone App with Swift Improving Our User Interface Changing the Background Color

Kind of stuck here. Not sure where backgroundColor property is meant to go.

I need to access UIViewControllers property of backgroundColor and apply UIColor instance to it?

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.

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

Hey buddy so the compiler needs to know who or what object's view and background color your changing. I'm assuming that you mean to change the background of the main view so, in order to tell the compiler you want to do this you can say something like:

 self.view.backgroundColor = blueColor 

I hope this helps...
