UIColor

PLEASE HELP I'm trying to figure out why I can't move to the next task. It keeps saying to add to the value of blueColor UIColor.blue but I'm not sure what I'm doing wrong.

ViewController.swift
class ViewController: UIViewController {
  let blueColor = UIColor(red: 0/255.0, green: 0/255.0, blue: 255/255.0, alpha: 1.0)
  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.
  }
}

Since UIcolor has a property for blue, you don't need to use RGB values

var blueColor: UIColor = UIColor.blue
