Creating UIAccessibilityElements, combined with a semanticGroup accessibilityContainerType, can also help you make components as complex as charts accessible.
Example from "Bring Accessibility to Charts" WWDC21:

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.
SwiftUI has equivalent accessibility modifiers for some of UIAccessibility's properties in UIKit. Same basic concepts apply.

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
Here's a few examples where Apple seems to use the semanticGroup accessibilityContainerType, other than for the tab bar and toolbar, to serve for inspiration on when it might be useful in your own apps. Reminder that this configuration causes for VoiceOver to announce the accessibility label of the container view, before what it would normally announce for an element, only when the focus moves from outside to inside the container.
