Multiple crash reports when running new app on Xcode 12 simulator

No one has figured out a good way to fix this yet. Please submit a bug report to Apple, using both macOS and simctl to generate sysdiagnose files:

xcrun simctl diagnose
sudo sysdiagnose

This is a fundamental problem affecting a lot of people, where the simulator daemon processes are crashing right and left, and the only way to get Apple's attention is to submit bug reports. But submit the sysdiagnose files so that they can figure out what's going on.

In the interim, you can download the older iOS simulators, e.g., 13.5, and you will get fewer daemon crashes. But you'll need to use the Xcode 12.0 installation because Apple broke the simulator downloads when they released Xcode 12.0.1.

I got some peace on my private Mac by downloading the "Additional Tools for Xcode 12" and use Utilities/CrashReporterPrefs to set Crash Reporter to the "Basic" mode.

@TomE You are absolutely awesome. Thank you. While I really wish Apple would actually prioritize fixing their core bugs instead of relying on the lottery to groom their backlog, this at least lets me get my automated tests running again.
