Show keyboard automatically when UISearchController is loaded

Question

I created a UISearchController in a table view controller. I segue to this table view controller using a push segue from another view controller. I want the keyboard to show up

Answer 1

Swift 5

1. in viewDidLoad:

searchViewController.delegate = self

2. in viewDidAppear:

searchViewController.isActive = true

This activates the SearchController

3. Define a delegate method:

extension MyViewController: UISearchControllerDelegate {
    func didPresentSearchController(_ searchController: UISearchController) {
        DispatchQueue.main.async {
            searchController.searchBar.becomeFirstResponder()
        }
    }
}
