XCUITest - Failed to find matching element

Question

In one of my view controllers, I have code like:

class ViewController: UIViewController {
    @IBOutlet weak var _tableView: UITableView!

    private lazy var searchBar: UISearchBar = {
        let searchBar:UISearchBar = UISearchBar()
        searchBar.isAccessibilityElement = true
        searchBar.accessibilityLabel = "SearchField"
        searchBar.placeholder = "Search..."
        searchBar.sizeToFit()
        searchBar.isTranslucent = false
        searchBar.autocapitalizationType = .none
        searchBar.returnKeyType = .done
        searchBar.delegate = self

        return searchBar
    }()

    override func viewDidLoad() {
        super.viewDidLoad()

        isAccessibilityElement = true
        accessibilityLabel = "ViewController"

        _tableView.isAccessibilityElement = true
        _tableView.accessibilityLabel = "ItemList"
        _tableView.tableHeaderView = searchBar
    }
}

Now whenever I try to record UI test and select the searchBar, I get the following error:

Timestamped Event Matching Error: Failed to find matching element

I tried debugging to get the searchBar and following code, but it didn't match any element and assertion fails.

    let searchField = app.tables["ItemList"].otherElements.element(boundBy: 0).otherElements["SearchField"]
    XCTAssertTrue(searchField.exists)

Can you please show me what I did wrong? How can I access and test the searchBar? Thanks in advance.

You can use the Debug View Hierarchy or the XCode open developer tool Accesibility Inspector from bottom to top looking for the view that isn't accessibility enabled.
