ViewWillDisappear not getting called searchcontroller

Question

When I\'m in the middle of a search and then switch UItabs, ViewWillDisappear does not get called. Any idea as to why ViewWillDisappear does not get called when I have filtere

Answer 1

Had the same issue. viewWillDisappear is not called on the UITableViewController, but it is called in the UISearchController.

So I subclassed UISearchController and overrode the viewWillDisappear method. In my case I just needed to deactivate the search controller.

class SearchController: UISearchController {

    override func viewWillDisappear(_ animated: Bool) {        
        // to avoid black screen when switching tabs while searching
        isActive = false
    }
}

Answer 2

Similar to @user5130344 I found that subclassing resolved my issue, although I found that isActive = false cleared the search bar where I wanted the search query to remain on returning to the view.

Here's my subclass instead - this fixed my issue with iOS 13 dismissing the parent view:

class MySearchController: UISearchController {

    override func viewWillDisappear(_ animated: Bool) {
        // to avoid black screen when switching tabs while searching
        self.dismiss(animated: true)
    }
}

I think its the problem with the xcode . Try to close it and reopen the project once again and try to run again
