Cannot set searchBar as firstResponder

To me, there’s a quite big lag when using viewDidAppear. It can be better to use becomeFirstResponder asynchronously in viewDidLoad (tested with iOS 10, Swift 3):

override func viewDidLoad() {
    super.viewDidLoad()

    DispatchQueue.main.async {
        searchController.searchBar.becomeFirstResponder()
    }
}
