I am getting a Fatal Exception: NSRangeException
*** -[__NSArrayM objectAtIndex:]: index 0 beyond bounds for empty array
But there is no call to removeObjectAtIndex, and this happens in different view controllers. I am just looking for ideas as to where to look since in lines 3-5 the App is given control but there are no symbols.
The crash log is from fabric/crashlytics and it only occurred around ~30 days from app release but the instance or number of crashes is relevant.

Most likely, the issue is related to outdated Javascript SDK.
Per our check, your Javascript SDK version is 2.8.1. Please update SDK to the latest version 2.12.9: https://github.com/QuickBlox/quickblox-javascript-sdk
Also, make sure that you are using the latest iOS SDK version 2.17.4: https://github.com/QuickBlox/quickblox-ios-sdk
Seeing a strange crash while listening
NotificationCenter.default.addObserver(self, selector: #selector(contextDidSave(_:)), name: .NSManagedObjectContextDidSave, object: nil)
#objc private func contextDidSave(_ notification: Notification) {
print(notification)
}
However, keeping below line and calling something else inside it not causing any issues.
Below code will work fine as we are not printing or consuming objects
if let updatedObjects = notification.userInfo?[NSUpdatedObjectsKey] as? Set<User>, !updatedObjects.isEmpty {
myMethod()
}
Already debugged by using NSZombiesEnabled, InstrumentsWithCoreData, Exception Breakpoints,ThreadSanatizer, "Arguments Passed on Launch" in -com.apple.CoreData.ConcurrencyDebug 1
Unable to get why it's happening. However i thought it's of property so I printed all property 1 by 1 it worked fine for me.
As per as my knowledge it's happening because of combination of Swift and Obj-C
It's a huge project so I am not sure what can be done?
Is there a way that I can get more info about object via it's reference mat be object name or another information, Somehow?

I have used a webview in my app. But i'm not sure why it crash.

Is there some faced the same problem, and how to fix it?
My app is experiencing a weird error which I cannot reproduce. I know the existence of this error because some users have reported it to me and I could catch it using the Fabric SDK.
Apparently it happens at any location, at any given time. It doesn't not happen a lot though, it seems to happen once in a while. I have no idea where to start looking for this, because I tried to catch the error running on multiple devices connected to my xcode project, but it just doesn't happen to me, or at least when I am looking for it. Can someone give me a light where to begin to look for it?

I am trying to debug this crash. It seems to be inside Apple's framework in description method but I don't know what it's causing it.
I'm using Restkit and Core Data. I get the crash as soon as the API returns a new model "Category" with array "products" empty.
Thank you

It means that you give an NSNumber-wrapped Boolean to CoreData when it expects a string.
Then apparently you use method swizzling which is a pretty bad idea and may lead to such crashes.
