// Do you often find yourself writing lines of code that look like this?
// let viewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewControllerWithIdentifier("ViewController") as! ViewController
// Here's a simpler way, using generics and Swift type-casting (as long as the viewcontroller's storyboard identifier is its class name).
// Now you can write: let viewController = UIStoryboard(name: "Main", bundle: nil).instantiateViewController() as ViewController

    func instantiateViewController<T: UIViewController>() -> T {
