Bummer: Make sure you're only adding properties specified in the directions

Can someone help me out with the code

ViewController.swift
class ViewController: UIViewController {

    let blue = UIColor(red: 0, green: 0, blue: 255, alpha: 1.0)

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

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

Nothing is wrong really, it’s just that the challenge specifically say that the property should be named “blueColor”, yours is named “blue”. So the code is correct...
