5,724 PointsCode not working, confused as to why
The complier keeps telling me "Make sure you assign a UIColor instance representing blue color to the backgroundColor property of the back view on UIViewController"
class ViewController: UIViewController {
override func viewDidLoad() {
let blueColor = UIColor(red: 0/255.0, green: 0/255.0, blue: 255/255.0, alpha: 1.0)
view.backgroundColor = blueColor
}
override func didReceiveMemoryWarning() {
// Dispose of any resources that can be recreated
}
}

71,830 PointsAmar, you have all the right pieces, but (1) the challenge asked you to create a stored property -- so it must be in the class, not the function, and (2) it asked you to pass int values except for alpha. That said, it also gives spurious error messages. Try this instead:
class ViewController: UIViewController {
let blueColor = UIColor(red: 0, green: 0, blue: 255, alpha: 1.0) //a stored property -- in the class
override func viewDidLoad() {
// Do any additional setup after loading the view, typically from a nib.
view.backgroundColor = blueColor
}
override func didReceiveMemoryWarning() {
// Dispose of any resources that can be recreated
}
}

5,724 PointsI had moved my code out of the function and it still did not work. But of course now it works.
Thanks for you help!
