Most of this code comes from an old PR that @fruitcoder put up #795 2 years ago.
When creating our array of accessibilityElements, we need to respect the value of
accessibilityElementsHidden
. If the value of this property changes, we need to invalidate the cached accessibility elements (unless we are in the experiment that doesn’t cacheaccessibilityElements
).I created a simple test app and made sure this matched UIKit’s implementation. I also added a test case that changes the value of
accessibilityElementsHidden
and makes sure the proper accessibilityElements are returned.
