If your watch app has good VoiceOver support, chances are you'll also have good Assistive Touch support. But an improvement you can make is to implement a quick action (triggered with a double pinch) when there is a main action you can perform.

Double-pinch quick actions on Watch

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.

Grouping elements when it makes sense can make a huge impact on easing navigation with some assistive technologies like VoiceOver, Switch Control, or Full Keyboard Access. It also helps on reducing redundancy.
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
Even when setting a view as modal for accessibility, you may notice that VoiceOver's focus stays in the same place, instead of moving to the presented view. You can post a screen changed notification and pass the view that should get the focus.
