I have been getting crash reports like this for a keyboard extension I have developed and am either confused about how to read the stack trace or why it is occurring or both and I was hoping someone could help me clear this up.
Below is the stack trace:

In the left column where it lists the libraries (correct term?) I don't see any reference to my code. In other crash logs there is always some reference to a class in my app or something but I don't see that in this one. What does that mean? Is the crash occurring before my code executes and this is an Apple issue I can ignore?
It's an Apple Bug. The keyboard extension I work on has a nearly identical crash report. Fortunately, this only seems to happen on iOS 8, though I have seen a similar one that affects iOS 9.
I would file a bug report with Apple, and include a copy of the stack trace.

I try to fix an error on firebase.
My sources are based on objective-c, and "webkit" is a problem in my code
I try and try to find what is cause of it, but I can't. Because these errors appears in a different places but same error.

I know it has only few clues for finding. Sorry.
My codes have a lot of request datas to Server and response from Server on mainthread.
I expect it occurs this problem but I'm not sure.
Thanks.

I have checked on various platforms for this issue. But have not found any solution related to it.Please provide any solution related to it.
It is crashing on app launch itself and this is the report it shows on fabric
I've the same issue on iOS 13 and it's my most serious crash on Crashlytics.
It occurs only in iOS 13 and above. Unfortunately also in the latest 13.1.2.
Starting by the iOS 13 release I've detected a strange warning when I put my app in background the debug console print Can't end BackgroundTask: no background task exists with identifier x, or it may have already been ended. Break in UIApplicationEndBackgroundTaskError() to debug.
Maybe the issues are related.
So I am receiving Crashlytics crash report for my iOS App. For some of the users the app has been crashing giving SIGABRT in the crash log.
I have been trying to find the cause of this error for countless hours but due to rarity of the error (around 1-2% users) I have been unable to reproduce the error and, due to limited amount of information from Crashlytics, I have been unable to find the root cause of this error.
The deployment target is iOS 7 for the app and devices of all sizes with iOS 10+ are experiencing the crash (I am not sure if iOS 9, 8 or 7 are also experiencing the error — Crashlytics is only showing crashes on iOS 10+)

I would be extremely grateful for any kind of assistance. I would also be grateful if I can get any kind of pointers for reproducing Crashlytics errors.
Updating the Question with Code
In the controllerDidChangeContent: mainly the table view is ending updates.
- (void)controllerDidChangeContent:(NSFetchedResultsController *)controller {
[self.tableView endUpdates];
if(controller.fetchedObjects.count == 0){
self.showsNoMatchesHint = YES;
}
else{
self.showsNoMatchesHint = NO;
}
}
Given the last gasp of your program was in _endCellAnimationsWithContext, and these types of animations usually occur on completion of cell editing, I'd look into problems when that particular table is completing a cell edit operation. There's a picker view and a notification also going on in there, so that should narrow it down some. Good luck.
It looks like caused by this line of code
[self.tableView endUpdates];
I would suggest you to make sure the logic of -(NSInteger)numberOfSectionsInTableView:(UITableView *)tableView is correct. For example, it doesn't return 0 while the array is empty. Good luck.
About 10+ crash reported by crittercism.
Name: SIGSEGV
Reason: SEGV_MAPERR
Seems it is a UIScrollView/UITableView animating or scrolling issue.
How can I find the root cause?

I've seen this happen when a controller and/or its table is deallocated during an animation. The OS still triggers delegate methods (e.g., -scrollViewDidEndScrollingAnimation: or -scrollViewDidEndDecelerating:) when it finishes with the animation, but because the objects no longer exist things get weird.
The best fix is to nil the delegate in the controller's dealloc method.
I'm using Crittercism (SDK 4.1.2) crash reporting service to catch reports on my iOS app. i've been getting this crash many times and i've no idea why it's happening.

Not sure if this is the case for you, but I've had a similar crash caused by a button in an UIView trying to invoke a callback method on a already released object. The UI was displayed, and then the object was released.
