Our App runs well in iOS 12, but recently we found on iOS 13 beta there are some rare crashes. I spent a lot of time investigating it, but I still haven’t solved it. Can anybody help me.
Are you using NSFileProtectionComplete in your entitlements? We found a *strong* correlation between using NSFileProtectionComplete and the crash, which would happen soon after device lock.
We were able to temporarily work around this issue by switching to NSFileProtectionCompleteUntilFirstUserAuthentication, then locking specific directories with NSFileProtectionComplete.
