I found crash reports from Apple that point to a crash related to Core Data. I only found crash reports for iOS 13.3 and did not see any for previous versions of iOS.
My app uses XMPPFramework for some years now, but this problem is very new to me and it seems that the problem came with iOS 13.3.
Unfortunately I am not able to reproduce the crash.
Hello,
I found crash reports from Apple that point to a crash related to Core Data. I only found crash reports for iOS 13.3 and did not see any for previous versions of iOS. My app uses XMPPFramework for some years now, but this problem is very new to me and it seems that the problem came with iOS 13.3. Unfortunately I am not able to reproduce the crash.
