Good day,
I have an app with CoreData that is in the Apps Store. I have now coded some cosmetic changes in the interface without changing anything in the CoreData model. I did not add/delete/or change any entity or property. Now, I am ready to upload my version 2 of the app. I am unsure whether I have to do anything so that the old data of the users in the first version will not be deleted but will be saved in the new app (with exactly the same CoreData model). Please be tolerant with this noob.
Great thanks,
Romeo
