Question

Given the following console output, why is my Core Data save failing?
It seems that the biz entity is empty. I have 20 “biz” entities, and only 1 is most likely empty. Why does the whole save fail?

Why doesn’t Core Data just save all that works and ignore the empty entity? Instead, it returns Error in saving Error in Saving Error Domain=NSCocoaErrorDomain Code=1570.

Here’s my console log:

Answer 1

This previous answer explains it best. To quote from the accepted answer:

It means there’s a mandatory property has been assigned nil. Either in
your *.xcodatamodel check the “optional” box or when you are saving to
the managedObjectContext make sure that your properties are filled in.
