Hi!
There is a weird crash what I cant reproduce. 5% of or our users (20-30 crash/day) have this random crash. So I want to fix it. But I have no idea what I should do with it. Reports come from only iOS 12
Here is the stacktrace from Instabug. Do you have an idea what can cause this crash?
data:text/text;charset=utf-8,
# Cause: Crash due to signal: SIGSEGV(SEGV_MAPERR) at 00000058
# Reported at: 2018-12-13 20:07:40 UTC
