Post the crash log. (the header and crashed thread, at least - don&#x27;t need the long list of binaries)If it is symbolicated, it should contain the source file and line number if any of your code is involved in the crash. If it&#x27;s not symbolicated, drag it into the Device Logs view in Xcode&#x27;s Devices window when you have a device connected. Xcode should then symbolicate it.

Perhaps you missed the part where I suggested you symbolicate the log. If you do so, this line0   Rest on Work                   0x0000000100094e54 0x100088000 + 52820will indicate the source file and line of code at which it crashed. That&#x27;s usually a pretty good clue what the problem was.

OkI think i found my mistake.After i fix it, do i need to start my app submission process from the begining or i can resend the fix IPA file?

Good work. You just need to upload the new binary from Xcode, then after the build has finished processing (usually just a few minutes) go to the new app version in iTunes Connect, select the new binary you just uploaded, save and Submit for Review again. Unfortunately a new binary always means a whole new review cycle (they don&#x27;t know what else you may have changed).
