How to let search bar disappear immediately when moving to another VC - swift

Question

Below Gif is from my app, the 1st VC includes a search bar to filter the songs, and when press a row to transition to 2nd VC to show selected playing song.
The question here is that when 2nd VC is opened, the search bar is not disappeared immediately, it has like 1 or 2 seconds delay, could see that behavior from below GIF.
/ / / Here is my code, how could I solve this issue? Any hint is appreciate.
The search bar
var resultSearchController = UISearchController()
override func viewDidLoad() {
...
// add search bar
resultSearchController = ({
let controller = UISearchController(searchResultsController: nil)
controller.searchResultsUpdater = self
controller.hidesNavigationBarDuringPresentation = false
controller.dimsBackgroundDuringPresentation = false
controller.searchBar.sizeToFit()
// set search Bar covered color, same with tableView's background color.
controller.searchBar.barTintColor = UIColor(rgb: 0x292f33)
self.tableView.tableHeaderView = controller.searchBar
return controller
})() // closure, learn it later!!
...
}
I set search bar to disabled state when leaving current VC.
override func viewWillDisappear(_ animated: Bool) {
super.viewWillDisappear(true)
resultSearchController.isActive = false
}
/ / / Update, as matt's comment, I change the code to integrate search bar into navigation bar, and now the search bar is disappear immediately after opening VC2.
remove self.tableView.tableHeaderView = controller.searchBar and integrate the search bar into the nav bar navigationItem.searchController = resultSearchController. Now the behavior is same as Apple's inbox app.

Answer 1

searchController.searchBar.isHidden = false
Hiding the searchController instead of making the active state to false may solve your issue.
Try adding in the above line to your code in viewWillDisappear()
hopefully this helps.
