Whose view is not in the window hierarchy after dismissViewController

Question

I have a view controller that shows the details of an object. On this view controller is an "edit" button which shows modally the edition view controller. When I try to dismiss the modally presented view (edit view controller) :

self.dismissViewControllerAnimated(true, completion: nil)

I get the following error and it's presenting my initial viewController instead :

Warning: Attempt to present ≤Deevent.MyEventsVC: 0x7f99b70160a0≥ on ≤Deevent.EventCreationVC: 0x7f99b7238690≥ whose view is not in the window hierarchy!

So what I've tried was to set the root view controller of my view to the view I wanted to go back and present it in the completition of my dismiss. It's working well, but my application is in a Tabbar Controller and now it's not in it anymore. Same for the navigation controller.

let storyboard = UIStoryboard(name: "Main", bundle: nil)
let vc = storyboard.instantiateViewControllerWithIdentifier("MyEventsStoryboard") as! MyEventsVC

let appDelegate = (UIApplication.sharedApplication().delegate as AppDelegate)
appDelegate.window?.rootViewController = vc

self.dismissViewControllerAnimated(false, completion: {
                    self.presentViewController(vc, animated: true, completion: nil)
                })

Is there an other approach for presenting viewControllers after dismiss without leaving the Tabbar controller ?

Thanks

When I try to dismiss the edition view controller, I get the error and instead of showing me my details view controller, it shows me my initial (login) view controller. — Nicolas Meienberger
share the code where you are presenting view controller modally — Ajay Beniwal
It's just a performSegueWithIdentifier : self.performSegueWithIdentifier("editEvent", sender: self) — Nicolas Meienberger
For the error that you are getting, have you checked stackoverflow.com/questions/11862883/… or stackoverflow.com/questions/28379327/… — Guy Daher

Since you are trying to present the new view controller by calling self.presentViewController after you dismiss self, you get the error. I can offer you a solution if you are using a navigation controller.
