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.

When creating AXCustomContent objects for accessibilityCustomContent, you can specify the importance of the data. If it is high, it will always be presented by VoiceOver. You could potentially ask the user if that data is of importance to them.
Grouping elements in SwiftUI is extremely easy! You can use the .accessibility(children: .combine) modifier. And that's it! It merges properties. For example, generating an accessibility label by joining the children's ones, separated by commas.
It can help to alert the user of something that happened, in a part of the screen that is not currently on focus, and that is not important enough to disrupt the user by moving VoiceOver’s focus to a different place. It can be useful to announce certain messages like errors or long running tasks that have finished (i.e. a download that finished) or with custom notifications and snack bars.
