When adding UISearchController to a UITableViewController's navigation item, refresh control becomes invisible.I could not find any official info on whether iOS 13's behavior has changed in regards to search bars or refresh controls, and/or what I have to change to make it work, so I assume this is a bug.The bug is easily reproducible with Xcode 11 Beta on both iOS 13 Beta 1 and Beta 2, as well as when running apps built with Xcode 10 on iOS 13 Betas. The same code works perfectly fine on iOS 12 and older: refresh control gets embedded in a navigation item and is visible and animated as expected.1. Create a Storyboard with a simple navigation stack: UITableViewController embedded in a UINavigationController2. Enable refreshing for UITableViewController3. in viewDidLoad method, create UISearchController and assign it to the self.navigationItem.searchControllervar searchController: UISearchController! override func viewDidLoad() { super.viewDidLoad() searchController = UISearchController(searchResultsController: nil) navigationItem.searchController = searchController // This doesn't change anything, but I added it to be consistent with official code for UISearchController definesPresentationContext = true }Without search controller embedded in a navigation item, refresh control is visible and working as expected. With search controller, refresh control still seems to be functioning and sending control events, but it's invisible on the screen.Can someone confirm if this is a known issue or if I'm doing something wrong here?
