On: The Multiple SQLite Problem

[sehugg]

Core Data uses SQLite as its backend by default, so you may still potentially run into these kind of problems -- if say, an ad network decided to statically link in its own SQLite version.

I have been frustrated by persistent corruption in a production app that solely uses CD, though I don't know if it's related to multiple SQLite instances.

EDIT: An ad library is probably a bad example since it wouldn't create files that are normally touched by the user app. Unless you were making an app to visualize ad library requests...

Yes, I think sehugg understood that, and the point was that even if you are diligent about solely using CoreData, someone else, like your ad provider, might introduce another version of SQLite in their library, so you'd be screwed anyways.

No you wouldn't. You'd only be screwed if you used that other copy of SQLite to open the SQLite file used by CoreData to store data. Which you shouldn't be doing anyway.

I fail at reading comprehension.
