We have rarely occurring set of crashes (1.5%) appear in considerable quantities and below are screenshots of Crashlytics reports.
I cannot reproduce any of these myself, and none of the app symbols appear in stacktraces. We have UI actions logging implemented, however following users' steps neither helps to understand nor to reproduce the issue.
Heavily used 3rd parties: AFNetworking
, SDWebImage
App is written in obj-c
How do I approach tracking down something like this?
Thanks
The reason was SDWebImage
version 4
cocoapod. After downgrading to 3.8.1
all these crashes disappeared.
