ios - QuincyKit/PLCrashReporter: provide description *before* the crash

Question

I'm using QuincyKit, which runs on top of PLCrashReporter, to discover production crashes in my iOS app, and to obtain logs. Sometimes, it'd tremendously help me debug if I had some variables from several call stack levels above the crash point. Like, what record ID did it crash on, if the record processing code is many levels of nesting deep.

The question is - is there a way to provide some kind of context string that gets inserted into a crash log as description at generation time? I'd set it upon entry into a call stack for a record, I'd clear it upon exit. Better if it's non-persistent (i. e. in memory) - writing to the nonvolatile storage all the time would be taxing on the battery, I'm afraid.

No, but the feature was proposed over 2 years ago and there's a patch.

I'd actually prefer a version that allowed logging the contents of a ring buffer (which you could efficiently log messages to!), which seems potentially much more useful.
