App crashes during startup when executed as IPA

[Oliver Goretzki]

Hello guys,

I'm facing a problem for a couple of days deploying my libgdx app on my iPhone for a couple of days know and I'm running out of ideas what could cause it.

Whenever I upload my app as an IPA on various iPhones it starts up showing the splash screen, hangs for a couple of seconds and then crashes.

The bizarre thing is that it runs perfectly fine when I execute the app directly from Eclipse (on both the simulator and real devices). The problem appears only when I execute the app as an IPA.

Here is the entry from the device log:

Apr  7 22:45:07 My-iPhone backboardd[28] <Warning>: Application ‘UIKitApplication:com.blabla.mygame[0xba3c]' exited abnormally with signal 11: Segmentation fault: 11

And the first part of the crash report:

Any idea what went wrong here?

Please provide a symbolicated crash log. It may provide a clue to what is happening.

Have you tried cleaning, uninstalling the app, and deleting the .metadata build cache? Then re-build to the device from eclipse. I had a resource problem like that which was first found in the IPA, that's a possibility.

[Oliver Goretzki]

I followed Eric suggestions by deleting the build cache but it doesn't seem to fix the issue. 

I spent hours yesterday to figure out how to symbolicate the crash but without success. I followed Niklas guide (and also tried a couple of scripts I found online) but it doesn't seem to symbolicate the crucial part in the crash report.

I notice that there is a newer conversation thread going on regarding symbolication, so I will try out those suggestions tonight and keep you guys posted what worked for me (or not :-) )

I'm having basically this same issue, where the IPA app crashes during the launch and the crash report seemingly can't be symbolicated. I thought I saw the converted lines via the atos command, but i'm not sure they were correct :/ i'll update this if I find any way to figure out why it is crashing.

[Eric Nondahl]

I found the cause of my boot crash via adding logging to the LibGdx AssetManager error() method. It was a resource issue in the IPA caused by an issue in my build script. 

It would still be nice to be able to read the IPA crash log, I can imagine a case in the future where it would not be so easy to find the cause of the crash without the crash log.

[Niklas Therning]

So it seems like Apple's symbolicatecrash script fails quite often? Did you use the exact same dSYM folder that was created when you generated the IPA?

Yes, I was using the correct dSYM when attempting to symbolicate

[Eric Nondahl]

Also, for what it's worth, i've been using TestFlight to send beta builds of our game to testers.  They are receiving crash reports, and it looks like their dSYM crash symbolication also fails on a RoboVM IPA.
