So I'm not sure if my code is even correct for this challenge.
class ViewController: UIViewController {
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.
}
view.backgroundColor = blueColor
let blueColor = UIColor(red:0/255.0, green: 0/255.0, blue: 255/255.0, alpha: 1.0)
}

class ViewController: UIViewController {
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 = UIColor(red:0/255.0, green: 0/255.0, blue: 255/255.0, alpha: 1.0)
view.backgroundColor = blueColor
}
Hope this helps. If so mark has the best answer.
