Hi team,
We have developed one IoT project in that we have used apple's core database for storing all app-related settings, IoT device settings. In that we are facing some unusual crash (EXC_BAD_ACCESS) whenever we are performing saving, retrieving & updating operations it's causing random issues. So please help me out to fix this issue.
turn on all these flags and see if the debugger points you to an issue in your code.

For me it was the name of an CoreData entity attribute. It is not allowed to start an attribute name with "new...". Nothing in Xcode does tell you that and it took me days to find out. I just got the EXC_BAD_ACCESS error.
Just wanted to leave this here for the next poor soul facing my specific problem ;)

I came across this article that lead me to the solution: https://alexj.org/11/core-data-attribute-naming
