How to dismiss any popover viewcontrollers when activated in iOS?

Question

I have some ViewControlls for settings, info etc. Users can close the app settings ViewController open(I mean popover the ViewController). When local notification is received I want the the app go to the root viewcontroller and dismiss any popovers.

EDIT this answer is only good if the VC you are trying to go back to does not need any special initialization, since this method creates a new instance of it. keep that in mind.

Try this method, it will remove anything in your stack of View Controllers and make a specific View Controller presented on screen:

func dismissAllAndNavigate(){


    let appDelegate = UIApplication.shared.delegate as! AppDelegate
    let window = appDelegate.window
    let mainStoryboard: UIStoryboard = UIStoryboard(name: "Main", bundle: nil)
    let rootController = mainStoryboard.instantiateViewController(withIdentifier: "some identifier") as! UIViewController
    window?.rootViewController = rootController

}

Just make sure that the name of the storyboard is correct and the identifier of the view controller in that storyboard is defined.
