The header accessibility trait makes VoiceOver announce something as a header. More importantly, it lets the user navigate through headings, swiping up/down, significantly speeding up navigation and making it easier to explore/discover content.

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.

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.
VoiceOver has a very cool gesture called the Magic Tap (double tap with two fingers). It should execute the most important task for the current state of the app. Examples: start/stop timer, play/pause music, take a photo, compose a tweet... You just need to override accessibilityPerformMagicTap() to capture that gesture, execute the desired code, and return true if handled successfully. https://developer.apple.com/documentation/objectivec/nsobject-swift.class/accessibilityperformmagictap()
When interacting with a button with VoiceOver, the accessibility label is repeated to the user. If you are playing some audio, it could be difficult to listen to it properly. To avoid that, you can add the .startsMediaSession accessibility trait.
