If a view has isAccessibilityElement to true, assistive tech won't look for any of its subviews. That means that if there are any buttons inside, they won't be accessible. You can add custom actions to that element though.

Sometimes you want to prioritise ease of navigation, and that's when configuring isAccessibilityElement to true on a container view makes sense. This is especially true in table/collection views and with complex cells with lots of elements. Take the example from a tweet (from Day 62's tweet). If the tweet has 9 accessible elements, you'd need 9 swipes to the right to go to the next tweet in the list. But ideally, I single swipe should be enough. https://x.com/dadederk/status/1549417799746994177 On the other hand, for the detail screen for a single tweet, you want to optimise for ease of access to each one of the elements, instead of navigation. In that case it would be better for the tweet view not to be an accessibility element.
When configuring a largeContentImage or adjustsImageSizeForAccessibilityContentSizeCategory, it is important to use a pdf asset and preserve the vector data so the icons are crisp at any size.
Too much data can overwhelm users. Very little is an incomplete experience. It is hard to find a balance on verbosity and the users may have different preferences. To help with this issue, the AXCustomContent APIs let you mark data as optional.
