I'll never recommend creating a custom component if there is a native one that does the job. But if you develop a custom tab bar, .tabBar accessibility trait comes to the rescue. Apply to a container view and its buttons will be announced as tabs.
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 both screenChanged and layoutChanged notifications signal changes in the UI and allow you to move VoiceOver's focus somewhere else, what's the difference? To the user, screen changed plays a sound indicating them they got moved to a new screen.
By its name, I misunderstood what shouldGroupAccessibilityChildren does the first time I saw it. It can be used for VoiceOver to traverse all items in a view before moving to the next one, instead of grouping as in combining those elements. VoiceOver traverses elements in the natural reading order, from left to right, top to bottom, in left-to-right languages. Sometimes data is displayed in columns, so that order might not be the most logical one. https://developer.apple.com/documentation/objectivec/nsobject-swift.class/shouldgroupaccessibilitychildren
If you are displaying something in two or more columns, you may want to change that to as little as one column when using some of the largest Dynamic Type settings to keep the text readable.
