I'm wondering if TestFlight users will be able to retain their data (in Core Data and User Defaults) after I migrate my app to iTunes Connect TestFlight, or if their app will be totally reset? (or if it will install to a different application icon)

Thanks

    The only way an app could install "to a different icon" was if app bundle id was changed. As long as you use same bundle id, signing identity and entitlements (if any), no data should be lost. – Filip Radelic Mar 08 '15 at 01:04

I tried it and it looks like NSUserDefaults and Core Data are retained no problem, with the same app name. However, TestFlight did give me a warning that app data might be deleted, so there could be other circumstances where data gets erased.
