And new in iOS 13, you can create actions that take an action handler instead of a target and selector. So you could write something like this:var userCustomAction = UIAccessibilityCustomAction(name: viewModel.userName) { (customAction) -> Bool in

var success = false

// Perform action

return success

}

accessibilityCustomActions?.append(userCustomAction)

When doing this, a hint saying “Actions available” gets vocalized by VoiceOver. When swiping up and down, those configured actions get read and can be actioned with a double tap. With the code example, a swipe up would say “Share,” another swipe would say “Like,” and if double tapping it would execute likeButtonPressed(_:).

And because it is an array of actions, you can always append more of them if the configuration changes:// Append more custom actions

accessibilityCustomActions?.append(UIAccessibilityCustomAction(name: viewModel.userName, target: self, selector: #selector(userButtonPressed(_:))))
