I'm adding search controller like this:
viewController.navigationItem.searchController = searchController
viewController.navigationItem.hidesSearchBarWhenScrolling = false
viewController.definesPresentationContext = true
searchController.dimsBackgroundDuringPresentation = false
searchBarContainer.translatesAutoresizingMaskIntoConstraints = false
searchBarContainer.heightAnchor.constraint(equalToConstant: 0).isActive = true
and when try to swipe right to pop current viewController (interactive pop gesture activates here) but stay on the same controller the search bar just disappears.
viewController.navigationItem.searchController
holds added search controller but it's not visible.
