If you embed navigation controller to your view controller then you can use this code:

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("ViewController")
let viewcontrollers = self.navigationController.viewControllers
viewcontrollers.removeLast()
viewcontrollers.append(vc)
self.navigationControllers?.setViewControllers(viewcontrollers, animate: true)

This is how I do it in Swift 2.1 with my Home view inside a UINavigationController:

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let homeVC = storyboard.instantiateViewControllerWithIdentifier("HomeViewController")
self.navigationController?.presentViewController(homeVC, animated: false, completion: nil)
self.navigationController?.dismissViewControllerAnimated(false, completion: nil)

You can change rootViewController of your application:

UIApplication.shared.keyWindow?.rootViewController = UIViewController()
