Unable to symbolicate crash reports

Question

I submitted a new version of my app to AppStore and it got rejected due to some crashes that I never experienced while testing the app.

Unfortunately I can't seem to be able to reproduce the issue so all I have to analyze the 2 unsymbolicated crash logs (.txt files) they sent me. However, I am having problems symbolicating them.

Crash Log 1

Crash Log 2

I tried following the steps provided HERE and HERE, as well as other suggestions but no luck.

Here are the things I tried so far:

$ atos -arch arm64 -o Qlear.app.dSYM/Contents/Resources/DWARF/Qlear -l 0x1839fa000 0x0000000183a1c2e8

Unfortunately the command returns only 0x00000001000222e8 (in Qlear)

$ atos -arch arm64  -o 'Qlear.app'/'Qlear' 0x1839fa000
$ atos -arch arm64  -o 'Qlear.app.dSYM/Contents/Resources/DWARF/Qlear' 0x1839fa000

Both commands return 0x1839fa000

$ dwarfdump --uuid Qlear.app.dSYM
$ dwarfdump --uuid Qlear.app.dSYM/Contents/Resources/DWARF/Qlear

Both commands return

UUID: 4FFCBD15-01BA-366A-8C28-E4E613401616 (armv7) Qlear.app.dSYM/Contents/Resources/DWARF/Qlear
UUID: 97BD48FC-11E3-37C9-A081-700DCE0CDB23 (arm64) Qlear.app.dSYM/Contents/Resources/DWARF/Qlear

If I try $ dwarfdump --lookup 0x1839fa000 -arch arm64 Qlear.app.dSYM I get:

----------------------------------------------------------------------
 File: Qlear.app.dSYM/Contents/Resources/DWARF/Qlear (arm64)
----------------------------------------------------------------------
Looking up address: 0x00000001839fa000 in .debug_info... not found.
Looking up address: 0x00000001839fa000 in .debug_frame... not found.

So in the end I thought the .dSYM files(I tried the one on my Mac as well as the one from iTunes Connect) are corrupted so I tried dwarfdump --all Qlear.app.dSYM but this seems to be working as it returns a lot of content.

Any ideas what I'm doing wrong here? Am I mixing up the commands, am I using the wrong hex?

Answer 1

Finally, after hours of searching I finally found a solution:

1. Change the crash logs extension from .txt to .crash.. This is very important since .txt files are not recognized. I was also unable to find any info on this while reading Apple documentation.
2. Connect an iOS device and start Xcode.
3. In Xcode, go to Windows > Devices and Simulators (Shift + CMD + 1)
4. Select the Devices tab and then View Devices Logs.
5. In the left pane, select This Device and then drag-n-drop the .crash files inside.
6. Wait for the files to load and get symbolicated. The logs can also be symbolicated manually after drag-n-drop: Right Click on the log > Re-Symbolicate Log.
