Why doesn't this change the back ground color

I don't understand what i'm missing here

ViewController.swift
class ViewController: UIViewController {
let color = UIColor()

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

  }

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


  }
  let blueColor = color.blue
  view.backgroundColor = blueColor
}

When your app load the view from the storyboard with all the default settings (including the white background color), it calls the viewDidLoad() method, so you can customize your view inside the viewDidLoad() method. So move the blue color code inside the viewDidLoad()
