I have a weird behavior when presenting UIViewControllers modally in iOS 13. The new presentation style that I've seen all across iOS 13 looks like this:
The presenting view controller appears behind the presented view controller. It is also shifted down to mimic a "stack"
Meanwhile, when presenting view controllers through my app, I keep getting this effect:
The presenting view controller doesn't move at all when presenting a new view controller
I use this code to present this view controller:
let controller = storyboard?.instantiateViewController(withIdentifier: "tutorial") as! TutorialController
controller.modalPresentationStyle = .pageSheet
controller.modalTransitionStyle = .coverVertical
present(controller, animated: true, completion: nil)
Here is my question:
I'm wondering why this is happening and if there is a way to present view controllers in the normal iOS 13 style (with the presenting view controller moving back).
Thanks in advance!

Turns out the problem was my view controller hierarchy. I was able to fix it by making the presenting view controller the root view controller of my app. First I set the background controller as the root view controller by calling
and then using my previous code
I presented the view controller. Thanks to everyone who tried to help!
