The first step is asking to create a property called blueColor of type UIColor and set it to the value of blue like this:

    let blueColor: UIColor = UIColor.blue

Then in step two, it is asking to change the background color of view to blue when view is loaded like this:

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