In SwiftUI there is a very useful modifier accessibilityElement(children:), that will do very different things depending on the AccessibilityChildBehavior passed as a parameter. There are three options: ignore (default), contain, and combine.

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.

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.
The equivalent of using a .semanticGroup accessibilityContainerType in UIKit, would be to use the .accessibilityElement(children: ) modifier with the .contain option in SwiftUI. Here's a refresher with some use-cases: https://x.com/dadederk/status/1558790851496742914

VoiceOver will traverse elements from left-right, and from top-bottom. If for any reason you need to change that order, in SwiftUI you can change the accessibility sort priority. A higher priority number in the container means it will go first.
