I am just about to update one application from me. This app uses Core Data for saving the data, which the user puts in.
Now I want to fix some bugs, which aren’t associated with Core Data at all.
What do I have to do that the User gets his data after downloading the Update?
I don’t think about Lightweight Migration, because I haven’t changed anything.
Do I have to add a new Model Versioning File? – I don’t know.
You don’t have to to anything. If the model and the data is not updated as part of the update, and you are storing the user’s data in the documents directory, then a new version of your app will just carry on using the existing data.
