UISearchController black screen

I have looked at other answers to this problem but they did not solve my problem.

This is my storyboard setup:

In my UITableViewController, if I set self.definesPresentationContext = true then the search bar will appear on every tab. If I don't, then the table will turn black after clicking search then switching to another tab and switching back.

Workaround 1: Dismiss searchController or set isActive to false in viewWillDisappear.

Problem: The search bar gets push down from the top every time I switch back and forth:

Workaround 2: Set searchController.searchBar.isHidden = true.

Problem: In my other tab which also uses UISearchController, it's not able to present the scope due to another search bar being already present (but hidden): Attempt to present <UISearchController: 0x7ff81ac0aa30> on <xxx.ViewController: 0x7ff81ac0a6f0> which is already presenting (null)

Using your Workaround 1, setting self.searchController!.isActive = true in viewDidAppear does the magic. You'd also need to restore the search bar text though.

I was having the same problem and was fixed, handling correctly the definesPresentationContext properly, so I just define this property to true in viewDidAppear and set it false in viewWillDisappear

override func viewDidAppear(_ animated: Bool) {
        super.viewDidAppear(animated)
        if(self.searchController == nil)
        {
            self.setupSearchBar()
        }else{
            self.definesPresentationContext = true
        }
    }

override func viewWillDisappear(_ animated: Bool) {
    self.searchController!.isActive = false
    self.searchController!.searchBar.removeFromSuperview()
    self.definesPresentationContext = false
    if(self.showingSearchBar)
    {
        self.rigthNavBarButtonAction()
    }
    super.viewWillDisappear(animated)
}

I hope this helps you
