I have an attribute which has a relationship with a sub attribute which has a property as follows :

When I navigate to different View Controller, Say B, I am deleting records of the subAttribute and inserting once again with some fresh new records.

And again when I come back to View Controller A and try to insert some Data on the above sub Attribute , it says

"Dangling reference to .null object".

Need some help on what am I doing wrong here.

Thanks.

Absolutely right , Whenever i insert data into CoreData Need to make sure that its not duplicating the data inside DB. – Sundar_Mob Jul 03 '14 at 04:34
So you managed to solve it? – Lord Zsolt Jul 03 '14 at 07:07
Nope , there seems to be sort of design flaw when they are inserting. – Sundar_Mob Jul 03 '14 at 07:14
