Hi All,

I have the issue where app crashes installed from app store on iPad with OS 10.3.3, but running fine from Xcode.

I have crash log, but there is almost nothing there. Here is what I have:

#0	(null) in _os_unfair_lock_unowned_abort ()
#1	(null) in _os_unfair_lock_unlock_slow ()
#2	(null) in 0x53e000 ()
#3	(null) in 0x53e000 ()
#4	(null) in free_tiny ()
#5	(null) in 0x53e000 ()
#6	(null) in 0x53e000 ()
#7	(null) in free_tiny ()
#8	(null) in 0x53e000 ()
#9	(null) in 0x53e000 ()
#10	(null) in free_tiny ()
#11	(null) in 0x53e000 ()

and so on repeating line 2 to 4

Maybe anyone has idea what should I do.

Many thanks,

Mike

Two things:

Most problems that show up only on the App Store are related to your build configuration. You need to test locally with a Release build. The best way to do that is to build an archive, which creates a Release build, and then use the Organizer to export that archive with Development signing so that you can test it locally.
As to the actual crash, the backtrace suggests that you have memory corruption issues, and for that I recommend the Standard Memory Debugging Tools.

Do we need to export with App Thinning and Bitcode to test it locally for simulating App store review team environment?

Thanks for the info btw!
