It probably didn't crash the phone during review. App Store review is a human tapping through your app's common flows, looking for specific things. You don't provide them with the source code, and they don't really look at the binary, so it's not difficult to use private APIs or hide things from reviewers.

For example, after being kicked off the App Store by sanctions, Russian banks have used "trojan apps" that show different apps inside Russia: https://appleinsider.com/articles/24/02/12/how-russian-banks...

The specific condition being the phone OS being modified with third-party code by exploiting iOS vulnerabilities. Yeah, I think Apple missed that one.

App reviews take on average less than a minute. The reviewer just signs in, taps randomly, and that's it.

I don't think Apple tests those conditions, they're not common.
