Debugging Crash Log from dSYM

Here is how to symbolicate iOS crash reports. Make sure the .app or .ipa and the .dSYM files are the same ones created at the time of the compilation.

Step 1

If you have an .app file
Place the .app file and the .dSYM file into a folder.

If you have an .ipa file
Rename it to a .zip file and extract it. It should create a directory called Payload with the the .app and .dSYM files.

Step 2

In terminal, go into the directory with the .app and .dSYM files and run the command.

atos -arch armv6|armv7 -o yourApp.app/yourApp address

Example:
atos -arch armv7 -o testApp.app/testApp 0x0006468e
