Cannot tap on Switch Component in e2e tests on iOS

Description: I’ve reported the issue in the detox repo over here: https://github.com/wix/Detox/issues/1896 thinking that it’s something related to detox, but it seems more like a bug in RN core.

Basically I have a detox test that fails randomly on the press of a Switch component. I can see the tap on the component, but the Switch is not responding. It seems to happen in around 20% of the cases.

Here is a gif:

That first tap wasn’t registered - all the other went fine.

Here is the repo that demonstrates the issue: https://github.com/compojoom/rnDetoxActionSheetBug/tree/switch-bug

after cloning run

$ yarn

$ detox build -c ios.sim.debug

$ detox build -c ios.sim.debug

If the test succeeds - rerun it several times.

As it can be seen from the js code: https://github.com/compojoom/rnDetoxActionSheetBug/blob/switch-bug/App.js#L29;L57 - it’s a pure RN app with just the Switch component on the screen.

Running the same test on android succeeds in 100% of the cases.

Moreover I’ve done the same test on a Native iOS app and there tapping on the switch component is always registered. So that’s why I’m excluding detox as the reason for the bug. Here is a link to the native project that doesn’t have this issue: https://github.com/compojoom/SwitchDetoxNative

Expected Results

I expect that the Switch component will respond to taps all the time in e2e tests.

Try longPress - I faced the same issue

ok, so longPress is the workaround? But we so far agree that this is a bug?
