I am making a application in which i use core data . Now in this i need to create a primary key same as we create in sqlite (auto increment type ). Is this possible with core data .If yes then how any link or suggestion so as how to proceed for the same.

Since core data is a persistance framework more than a general purpose database, it abstracts the primary key.
