This package enables the ability to natively symbolicate all of your crash logs.

Install the package and reboot. Done.

Now all of your crash reports located in the settings app should be symbolicated automatically without any hassle

Yes way.

I was exploring any possible methods to symbolicating iOS crash logs, I felt like there had to be a simpler implementation than the already-existent 3rd party methods, but was slightly doubtful I would find anything of substance, really because far more talented individuals had undoubtedly explored this.

Although, I got lucky, in a disassembly session I discovered a global domain titled “com.apple.CrashReporter“, and after quickly double checking, nothing with that domain existed within NSUserDefaults or within any particular file on disk.

The preference value for “DisableLogObfuscation“ was revealed within that disassembly, and after a mass search for any constants containing “Symbolicate“, I was able to find that the key “SymbolicateCrashLogs“ was a compatible fit.

As June 4, 2021, I was able to uncover a new value "ExtraInfo". Adding this value provides a backtrace for all threads rather than just the first 5.

The package itself just installs the final property list to iOS‘s global preference directory (/var/mobile/Library/Preferences is the mobile user directory, but I decided to direct the installation path to the root user preference directory /var/root/Library/Preferences. It's proven just as effective and solves an installation issue rather than adding an extra script), but in case you‘d rather just add the plist manually, here is an XML representation of the final file:

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
<dict>
	<key>DisableLogObfuscation</key>
	<true/>
	<key>SymbolicateCrashes</key>
	<true/>
	<key>ExtraInfo</key>
	<true/>
</dict>
</plist>

Since this package is just moving a propertly list to a specific directory for convenience, there is room to achieve this same result without any extensive system privileges, for this is really a native feature hidden in iOS. For example, if you were to reboot into a non-jailbroken state after installing this package, the effects would still apply. And even further than that, If you were to manually add this preference file to the Global preference directory, you can easily carry this enhanced logging ability throughout different iOS versions / devices (as long as this file is appended to a mobile backup and is applied to said devices)

Until I find out what processes have to be killed for this to take effect, you’re gonna have to reboot your device or run ldrestart, after that, crash logs should be symbolicated. Here is a side-by-side representation of the differences you should expect. I used FLEX to formulate these crash logs, they are both identical attempts to push a view controller that does not exist.
