How to debug crashes with question marks in XCode's organizer? - ios

Since our last release we're seeing weird crashes in the Xcode Organizer containing only question marks. I first thought that these were unsymbolicated crashes but Xcode says these are already symbolicated.
It looks a bit like this issue: https://github.com/firebase/firebase-ios-sdk/issues/5043 but only half of the list of crash reports contains something like this, the rest is even more empty..
Here's the text log (App name [REDACTED])

My symbolicated crash report looks like not symbolicated

My users are saying my app is crashing on iPhone 5. I tested it on simulator but there was no problem. But i am getting weird crash reports from iPhone 5 only. I guess the problem is real but i could not see any useful information from these crash reports.

Crash on iPad 2 - Unity3D / iOS

I'm working on an app that's already existing. This app works fine on an iPad Pro / iOS 10. I'm trying to get it to work on iPad2 / iOS 9.3.5.
I manage to build it with XCODE. I can play it well. BUT, when I load a specific scene, it crashes.
XCODE just displays "iPad was disconnected". The last Debug shows :
"Unloading 3 Unused Serialized files (Serialized files now loaded: 0)"
No warnings, no errors.
After many researches I figured this was a memory limit issue. So I proceeded to empty the scene piece by piece to figure what's causing the issue.
The scene is now empty (^^) and it still crashes. Below is the profiler memory for the empty scene.

Error Formulating Crash Report:

Thank you for reading me,
q

thank you Guru for your time,
It was indeed, memory related. I was loading a lot of GameObjects. A lot of these GameObjects were inactive so I thought they weren't taking a lot of memory.
I was wrong.
Rather than SetActive() methods, I now use the Instantiate, Destroy methods.

Crash Log symbolication IOS 8.1.2 in xcode 6.1?

I tried to rectify the crash using the crash report under "Windows->Devices->View Device Logs", but the crash log is full of numbers. I tried Re-Symbolicate option, but there is no change. "Exceptional Codes" data is also missing in the report. I'm using single Mac System to run the project and view the crash reports.So there should not be any problem about symbolification Any other way to symbolicate ?

iOS app crashed in thread wihtout app actions

My iOS application crashed. In crash log I've found such info:
Exception Type: EXC_CRASH (SIGABRT)

I have no idea how to interpret this. There are some additional actions happening in other thread but they looks ok. Any idea why thread which does nothing crashed?

iOS - Crash Log when open from lock screen

I'm getting a really weird behavior, my app crashes almost only with the device (I did manage to reproduce the bug on the simulator, but only twice), and only when it is not running from Xcode.
What happens is, I can, sometimes, reproduce the bug by closing the app from the multitask, opening it again, locking the screen fast and unlocking the screen.
Also I get different errors sometimes.

Also I think it has something to do with this method:
- [UIManagedDocument openWithCompletionHandler:]
because if I comment out this line (used to open the document when document.documentState == UIDocumentStateClosed), the crash stops.
Just to make it easier, that UIManagedDocument Singleton Code openWithCompletionHandler called twice and crashes is not the problem, because - [UIManagedDocument openWithCompletionHandler:] is not being called twice.
Also, just to be sure, I did try that solution, and didn't change anything.
I'm sorry for the amount of information, but I did try to write here only the most relevant ones, also only one of each type of error that I found.
Thanks for the help.

Below links explains how to symbolicate the crash logs. it sounds useful.
