You can check if some features, like VoiceOver, are on. Experiences should not diverge too much. It could be used to avoid auto-hiding UI elements. iOS probably checks this to show search fields by default, without having to pull them down.
From the documentation:

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.
Accessibility Labels are not just for VoiceOver, and Accessibility User Input Labels are not just for Voice Control. The latter will also help Full Keyboard Access users to find elements on the screen by different names. Good API design!
When building custom components, or if not relying on UIControl's attributes to configure state, it can be easy to forget to specify the right accessibility traits. These are indispensable for a good experience with VoiceOver, Switch Control...
If you have interactions that are hidden or require complex gestures to be performed or that may conflict with VoiceOver, you need to provide alternative ways of executing these actions. Custom actions can help a lot of times, but not always.
