A SwiftUI canvas that looks perfect but VoiceOver only reads “group” usually means accessibility semantics or notifications were never made explicit — pixels aren’t the whole contract.

Map roles explicitly: prefer accessibilityLabel / accessibilityValue for simple items; when you need deterministic semantics or hit-testing, consider a small NSViewRepresentable bridge and set isAccessibilityElement and accessibilityRole.
Expose a single, well-scoped accessibility element rather than hiding many subviews with accessibilityHidden(true) whenever possible.
For dynamic updates, debounce and post the appropriate AppKit accessibility notifications so assistive tech gets stable announcements instead of floods.
Test with assertions for role/trait presence and accessibilityFocused transitions — and validate behavior with VoiceOver on real hardware, not only the simulator.

Tradeoff: prefer pure SwiftUI for lower maintenance, but use a minimal AppKit bridge when you need deterministic accessibility or hit-testing behavior.

What tradeoff has surprised your team most when adding VoiceOver support to dynamic SwiftUI canvases? Let’s compare approaches and test strategies.
