Dismissing a viewController resets presenting navigationController

I have a UINavigation controller. The viewController contents is as follows

[RestaurantViewController, MenuViewController, ProductViewController]

In ProductViewController I call

self.navigationController?.present(sideViewController, animated:true, completion:nil)

This presents the view controller as expected. Now when I call self.dismiss/self.presentingViewController.dismiss from within sideViewController, the original NavigationController Resets to

[RestaurantViewController]

Why is this? I just want to dismiss and be returned to the presenting viewController

Test in a small clean project and you will see that the behavior you describe is not normal. Therefore you are doing something else that causes the navigation controller to pop/unwind back to the RestaurantViewController. But you have not described what that is; only you can find out. – matt
The problem must lie in what happens after controller is dismissed. You must have called popToRootViewController some where or you are using someone's library that calls this popToRootViewController – The Mach System
@matt You were right, I was calling some code that declared viewControllers being called inside a viewWillAppear function rather than a viewDidLoad therefore was resetting it. Thanks – mwild

Why not just present the controller from ProductViewController using 

self.present(sideViewController, animated:true, completion:nil)

Then dismiss using 

self.dismiss(animated: true , completion: nil)

Other than that there could be many things that could cause your issues. If you want a navigation controller on the sideViewController then create a navigation controller and set sideViewController as the rootviewcontroller and present the navigation controller.

let nav = UINavigationController(rootViewController: //SideViewController)
self.present(nav, animated: true, completion: nil)
