How to reset/restart viewcontroller in Swift?

Question

I want to have a button on my navigation bar "Reset" and I would like this to be connected to an IBAction to sort of "restart" the controller.

I have some segues from another controller that changes some aspects of the viewcontroller (that has a collectionview) and I want the user to be able to start over. Does anyone have any suggestions as to how to proceed?

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)

You can change rootViewController of your application:

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

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)
