Apple - how to persists data in TestFlight to production for my testers?

Question

I asked this in the Apple forum however there have been no replies.

I use SQLite database in my app. The data that is in my testers local db on the device. How do I get that data for my testers into their production version of the app after they download it from the app store.

AFAIK after publishing in App Store, Testflight users will be able to download app form store. It should work as regular update.

I think you may be missing my point. The local database of the app will get destroyed as its in a sandbox of the device set up for TestFlight; when the production version is downloaded does it not get its own new sandbox in which the database used in TestFlight will not be there? – Ichabod

No, Testflight apps don't have separate/own sandbox. It'll be treated as regular update (like from one version to another, both from App Store) so all your data will persist. Check out this thread #32656008 – Sholokhov
