Comment on CrashReportExtension by Bri

"I don’t know why they can’t just give you the crash report text or .ips JSON directly, though. It looks like you have to use Mach IPC with the corpsePort to get the backtrace for each thread and then use the extension API to symbolicate the addresses. Even then, I’m not sure you can get all the information that’s in a standard crash report, such as the Application Specific Backtrace."

It's always one step forward two steps back with Apple.
