Also having this issue, very similar looking trace.
App released 4 weeks ago was fine, attempting to release a new version of our app, only thing we changed was some copy.
Apple reported it crashed on iPad on iOS 13.1.3
React 0.60
Tested on iPhone 7 with iOS 13.1.3 with no issues, which is strange, but we're waiting on a new tablet to test iPad specifically.

Crash log EXC CRASH SIGABRT - iOS 10.3.2

Can anyone assist me on how to interpret this crash log? The app crashes when a user attempts to login using Facebook. I cannot duplicate this error and I`m new to debugging. Thanks

Interpretation of iOS crash log with -[UIApplication _cachedSystemAnimationFenceCreatingIfNecessary:]

My submission to the App Store was rejected due to a crash. However, I am unable to reproduce the crash on multiple hardware devices and simulators. I've symbolicated the crash log, and it seems the issue is occurring in an area of code where the app is fetching some data from a server and closing a UIAlertController that notifies the user to "Please wait..." Below is the crash log.

I would recommend double checking that you are not interacting with that UIAlertController (or any other UIKit API) outside the main thread (aka, Thread 0 above). Many UIKit APIs are designed to be used only from the main thread.
Worth noting that the crash happened on Thread 1…
If you are in doubt, wrap the call with:
DispatchQueue.main.async {
// Call UIAlertController code here...
}

Apple Crash log not able to replicate issue

We have been trying to submit an app with Apple for the last month and it keeps coming back rejected for small reasons. We are completely stuck with this last response and have no idea how to proceed.
They said the app crashed when creating a profile on our app. The problem is we thoroughly tested this on 4 different devices (iPhone 5, iPhone5S, iPhone 6S, iPad Air) and it works flawlessly for us.
They provided us a crash log but after hours of reading it and Googling we are coming up dry. Any help understanding what this crash log means will be a greatly appreciated.

Crash EXC_CRASH (SIGABRT) on iOS 8.4

I have a crash that only occurs on Apple review: when they try to login the app crashes.
I tested it with real iPhones in test environment and in Ad-hoc several times and the crash never occurred before.
After the review I made some research and I found some similar things and I have been trying out but I can't event simulate the same issue here (I also tried to change Xcode debug to release and he crash does not happen).
Here is what they said it happened at the review:
Upon further review and a fresh install of your app we continue to
find that your app crashed on an iPad running iOS 8.4 and iPhone
running iOS 8.4 when we:
1. Launch App
2. Input provided demo account credentials
3. Tap "Login"
4. Application crashes.
Here is the symbolicated log:

Do you use some third party control? It's not rare some controls crash when compiled for release.
You can try to turn off the code optimizations for the release build and test if it crashes.
Looks like it crashed at
0 PioNET 0x00000001000e3274 +[AFNetworkReachabilityManager sharedManager] (AFNetworkReachabilityManager.m:113)
That class, AFNetworkReachabilityManager, has something to do with if the network is reachable or not. Have you tried testing your application under different network situations, like no internet or poor internet connectivity? That might be where they're seeing the crash.
