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.
Some of you have asked me how you can support what I do. This would really help, and would be hugely appreciated:
Find these posts useful? Share them at work, on social media, or with anyone that might find them interesting. Let's spread the word!
Check out any of my apps or games: Xarra!, RetroRapid!, or Mestre!.
A download and a review go a long way. They're free by default. On the App Store, ratings and reviews really help more people discover them.
Finding any of them useful? If so, and if you can afford it, purchasing lifetime access to all features or subscribing lets me buy the coffee that keeps me caffeinated. Caffeine keeps me going to maintain the apps, bring in new features that I hope you'll love, and keep writing.

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.
If you are using SwiftUI to build your apps, there is a fairly basic but very useful Accessibility Inspector built right there in the Inspectors Panel, on the right side of Xcode.
Custom actions work with VoiceOver, Switch Control and Full Keyboard Access. They also do for Voice Control. You can say "Show actions for <item name/number>", and an action sheet with all options, numbered, will be presented to the user. For some use-cases, Voice Control users might not feel it is a big win. Navigation is not as big of an issue, and interacting with custom actions might be a bit trickier than with "exposed" buttons. But lots of times seems a fair compromise.
