The Core Data Programming Guide states that you should not access the SQLite file manually:

"Although Core Data supports SQLite as one of its persistent store types, the database format is private. You cannot create a SQLite database using native SQLite API and use it directly with Core Data (nor should you manipulate an existing Core Data SQLite store using native SQLite API)."

Yes.

is it possible ?

Yes.

if so, will apple approve the app ?

Yes.

is it against the apple guidelines ?

No.

Unfortunately, the question you're not asking is the most important:

should we directly access the SQLite database of Core Data

No.

The format is not public and could change. You don't know when it is accessed or what problems could be caused by messing around with it behind Core Data's back.
