Locating Core Data’s sqlite database on Mac OS X app

On OS X 10.7 Lion when the app is sandboxed, it is stored in:

~/Library/Containers/com.yourcompany.yourAppName/

The persistent store in Core Data is just a file. So it's most likely in your Documents directory if it's a user's document. If it's an internal store, then it may be in the bundle, or may be put somewhere like ~/Library/Application Support.
