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.
Custom actions work well with VoiceOver and Switch Control. It is also a way of speeding up navigation, and grouping all actions available for an item in a single place, with Full Keyboard Access. Focus an item and use the shortcut Tab (⇥) + Z.
With accessibilityRepresentation(representation:), you can create a custom component and it can be perceived by assistive technologies as the view you pass as representation. No need to manually configure accessibility attributes. It is one of the most interesting additions to SwiftUI to help you develop accessible UI components. If your custom component behaves similarly to a native one, this is the way to go. https://developer.apple.com/documentation/swiftui/view/accessibilityrepresentation(representation:)
A common example where you need to manually configure the button accessibility trait is for some table/collection view cells. These tend to be “buttons” that perform an action, like playing music, or bring the user to a different screen.
