Does a SQLITE database get reset on an app update?

I'm wondering whether to use CoreData or simple sqlite database for an iOS app. The app lets users add tons of data to the database and I want to make sure that if I use sqlite, the database won't get erased when开发者_StackOverflow中文版 the app is updated in the future. I know that CoreData doesn't get reset, does a sqlite file? If so, how can I prevent from it getting reset?

Thanks in advance!

Nothing gets reset when an app is updated.
