Apple评论小组提供的EXC_BREAKPOINT（SIGTRAP）崩溃报告

Question

I got this crash report from Apple Review Team, they said that the app crashed at lunch. I have symbolicate the crash log, double check the app version and the dSYM, but the first two lines after the Crash were not Symbolicated (Symbolicated crash at the end).

I haven't been able to reproduce the error by myself and this app has been tested by a lot of people and is currently been use by Beta testers, and non of them has reported this or any other crash. The same version of this app is approved on TestFlight but rejected for the Apple Store.

Here is the symbolicated log if some of you guys can give me some insight.

Thanks in advance

Answer 1

for the record I was able to find the crash and solve it, my App has been approved and is ready for sale!

In my case the crash was happening because I didn't take care of some functions when the user don't accept the App Location permissions, it crashes when trying to do a reverse geocoding.

For those having similar issues here I leave you some links that can help you resolve you Crash issue, and symbolicate the crash log.
