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 setting isAccessibilityElement to true, assistive tech like VoiceOver will stop looking for other accessible elements in that view hierarchy. So if we make a view accessible, its subviews, including buttons and labels won't be accessible.

If an image does not convey additional information, maybe it's just used to make the UI look more attractive, it makes sense for VoiceOver to skip it. UIKit: set isAccessibilityElement to false. SwiftUI: create a decorative image explicitly.
