Need Help with this code challenge

I need some help with this code challenge, I don´t know how to do it in the right way.

ViewController.swift
class ViewController: UIViewController {

let blueColor =  UIColor.blue

let backgroundColor = blueColor

  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.
  }
}

Hi David,

You've done the first part fine. Now, in viewDidLoad amend the backgroundColor property of the view to blueColor. Use dot notation on view:

class ViewController: UIViewController {
var blueColor = UIColor.blue
  override func viewDidLoad() {
      super.viewDidLoad()
      // Do any additional setup after loading the view, typically from a nib.
      view.backgroundColor = blueColor
  }

I hope that helps.

Steve.
