A simple UIStoryboard extension to easily instantiate viewcontrollers using Swift type casting. Raw

storyboard-viewcontroller-init.swift

// 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

extension UIStoryboard {
    func instantiateViewController<T: UIViewController>() -> T {
        guard let vc = instantiateViewControllerWithIdentifier(String(T)) as? T else {
            fatalError("Could not locate viewcontroller with with identifier \(String(T)) in storyboard.")
        }
        return vc
    }
}
