I am utterly confused...

I am confused on what I am exactly supposed to do. I keep getting errors overtime I try to follow the instructions.

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.
      let blueColor = color.blue
  }

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

You are pretty close. See the changes

class ViewController: UIViewController {
let blueColor = UIColor.blue

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

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

}
