Have you ever seen VoiceOver randomly focusing on elements of the previous view when presenting a custom modal view? That can be fixed by letting the system know that the presented view is modal in terms of accessibility.

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.
When presenting a UI component that overlays the existing UI, you may have found that VoiceOver starts to randomly jump between the overlaid UI and the elements underneath. To avoid that, you can set its accessibilityViewIsModal to true. When setting the accessibilityViewIsModal to true for a view, VoiceOver will ignore its sibling views, treating it as if it was a modal. Useful when presenting custom popups, popovers, modals, action sheets, etc. https://developer.apple.com/documentation/objectivec/nsobject-swift.class/accessibilityviewismodal
