Where is iPhone crash report UUID recorded?

Sometimes I am unable to symbolicate my application's stack frames in a crash report. This is because I do not have an older .app and .dSYM. I was trying to force XCode to use my newer .app and .dSYM as the app has not changed significantly. Is there a way to modify the UUID associated with the crash report?

Is the UUID stored in file's metadata inste开发者_运维技巧ad of in the file itself? Is there a way to change it to achieve what I am trying to do?

Thank you!

The UUID is never stored with the crash report. There are identifiers in the first few lines, but none of them is the UUID.

Also you can't re-symbolicating with dSYM of another build. Even if you don't change the app, the symbols in the new build can change.
