ios - Large Title collapsing at launch when UITableView not empty - Stack Overflow

I have a UITableViewController with a UINavigationBar with the property :

navigationBar.prefersLargeTitles = true
navigationItem.largeTitleDisplayMode = .automatic

I add in the UITableViewController a UISearchController with the easiest way :

private func setupSearchController() {
    searchResultsController = SearchResultsController()
    
    searchController = UISearchController(searchResultsController: searchResultsController)
    
    searchController?.searchResultsUpdater = searchResultsController
    searchController?.obscuresBackgroundDuringPresentation = true
    searchController?.searchBar.tintColor = R.color.primaryText()
    navigationItem.searchController = searchController
    navigationItem.hidesSearchBarWhenScrolling = false
    definesPresentationContext = true
}

If the UITableView is empty the UI looks good, but if I add at least 1 row, the simplest like this :

override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
    return UITableViewCell()
}

At launch the Large Title of the UINavigationBar is collapsed. If I scroll down the UITableView I get the Large Title back.

It looks like adding something to the UITableView make it scrolling. How can I prevent the UINavigationBar to be collapsed at launch?
