Underlying views will disappear once a modal covers them. To prevent this from happening, you need to set the UIModalPresentationStyle of the modal view controller to OverCurrentContext:

ModalVC.modalPresentationStyle = UIModalPresentationStyle.OverCurrentContext

The above answer is correct, but in my case my view controller is embedded in a navigation controller so it didn't work. This does:

vc.navigationController?.modalPresentationStyle = .overCurrentContext

I think the problem is that you're not presenting your UIVisualEffectsView modally, but the view controller, so the gray you see is the background color of the right view controller. You could change that to the same gradient as the left one and see if that works, or you will need to display your UIVisualEffectsView on your first viewcontroller.
