<})>

Example 4: Changing Background Colors

<override func viewDidLoad() {>
<    super.viewDidLoad()>
<    // Set the background color>
UIGraphicsBeginImageContextWithOptions(self.view.frame.size, false, 0)
let context  UIGraphicsGetCurrentContext()!
context.setFillColor(UIColor.red.cgColor)
context.fillRect(self.view.bounds, with: UIEdgeInsets.zero)
let image  UIGraphicsGetImageFromCurrentImageContext()
self.view.backgroundImage  image
<}>

Example 5: Changing Font Colors

<override func viewDidLoad() {>
