inputAccessoryView getting hidden on UISearchBar activation in UISplitViewController

Question

I'm facing an issue - when UISearchBar is activated then inputAccessoryView gets hidden and doesn't show up even after de-activation of UISearchBar searching in iPad.

Steps to the issue

1. Start UISearchbar editing
2. Cancel UISearchBar editing
3. Observe the inputAccessoryView visibility before and after editing

The solution that I found was to make the detail controller as first responder immediately after Searchbar ends editing. Below is the sample code for the same:

extension NSNotification.Name {
     static let SearchbarEndEditing = NSNotification.Name("SEARCHBAR_END_EDITING")
}

func searchBarTextDidEndEditing(_ searchBar: UISearchBar) {
    NotificationCenter.default.post(name: .SearchbarEndEditing, object: nil)
}

And in DetailViewController:

override func viewDidLoad() {
    super.viewDidLoad()
    NotificationCenter.default.addObserver(self,
                                           selector: #selector(handleSearchbarEndEditing),
                                           name: .SearchbarEndEditing,
                                           object: nil)
}

@objc private func handleSearchbarEndEditing(_ sender: NSNotification) {
    becomeFirstResponder()
    view.becomeFirstResponder()
}

It worked for me and hopefully, it works for everyone else as well!
