Receiving error message with saving to a Core data object in Xcode
I am receiving this annoying error message with saving to a Core data object in Xcode.
I have spent so much time to fix this problem but I could not find any way to resolve this issue.
Have any better way to fix this problem?
I would be grateful to you.
Thanks in advance.
