Accessibility Identifier of UIBarB… | Apple Developer Forums

Accessibility Identifier of UIBarButtonItem

Hi Team,
I am trying to setup accessibility identifier for backBarButtonItem.

I can not see the identifier in Accessibility Inspector.

Here are my findings:-

UIBarButtonItem is derived from UIBarItem which confirms the protocol UIAccessbilityIdentification.
Setting isAccessibilityElement to true does not work.

Here is my code

Code Block    func setUpBarButton() {
    let backButtonImage = UIImage(named: "icon-backarrow")
    previousViewController?.navigationController?.navigationBar.backIndicatorImage = backButtonImage
    previousViewController?.navigationController?.navigationBar.backIndicatorTransitionMaskImage = backButtonImage
    let backButtonItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)
    backButtonItem.isAccessibilityElement = true
    backButtonItem.accessibilityIdentifier = "leftItem"
    previousViewController?.navigationItem.backBarButtonItem = backButtonItem
  }

Code Block
func setUpBarButton() {
let backButtonImage = UIImage(named: "icon-backarrow")
previousViewController?.navigationController?.navigationBar.backIndicatorImage = backButtonImage
previousViewController?.navigationController?.navigationBar.backIndicatorTransitionMaskImage = backButtonImage

let backButtonItem = UIBarButtonItem(title: "", style: .plain, target: nil, action: nil)
backButtonItem.isAccessibilityElement = true
backButtonItem.accessibilityIdentifier = "leftItem"
previousViewController?.navigationItem.backBarButtonItem = backButtonItem
}

What can be the reason for not showing identifier?
