iOS Voiceover reads from covered UIWindow

Question

I have the following setup:

UIWindow 0, windowLevel 0, rootController is the main part of the app, and takes up the whole screen, isHidden is false, is not key window
UIWindow 1, windowLevel 1, rootController is an auxiliary screen, and takes up the whole screen with no transparency, isHidden is false, is key window

Problem:

When voiceover is enabled and I touch an area in window 1 that doesn't have an element that can be interacted with, but where window 0 does have such an element, it will select and read the element in window 0, even though window 0 is not visible at all.

Is there something I'm missing?

Turns out there are 2 ways to fix this:

Set accessibilityElementsHidden to true on window 0. Not ideal because it has to be restored when window 1 goes away.
Set accessibilityViewIsModal to true on window 1. All windows are siblings so this will ignore window 0 for accessibility purposes. I don't think this affects special windows like the status bar and keyboard. This is likely the best solution.

have you set `accessibilityViewIsModal` to `true` on the window itself (aka, the. `UIWindow` instance)? – goldengil Mar 10 '21 at 11:38
modifying window's accessibilityViewIsModal seems to be a good solution! – jegadeesh Jun 27 '22 at 07:37
