core data app does not load saved data.

weird problem.

wrote a core data app, worked great, until last week. Now it doesn't load any data.


the save files, (binary) seem to be intact (based on file sizes)

but when the file is loaded, there's nothing in the document window. I know. it sounds stupid. It sounds stupid to say it.


I can add objects, work with them, and save files. the files get saved with the data intact. Opening those files produces an empty document.


I have not overridden ANY app level methods. I literally do not have any of the loading or saving code IN my app at all... it's all inherited.

the data model consists Of a single entity, which has 0 relationships, and 4 String properties.

bindings all work flawlessly...


and the kicker:

the app worked just fine until a few days ago (OS update, is what i'm thinking controlled the timing) saving, opening, everything worked. No changes, no Compiles. It just stopped working.


but other Core data apps work just fine.


I tried looking at my code.... but there's little or no Code, and nothing that deals at all with loading files. I looked at the data model, nothing fancy in there. I looked at the XIB. everything seems to be in order. Anyone know what this is?

I seem to be having the same problem here... A working Core Data app until roughly the time of iOS 9.2.1, and then all of a sudden some of my new users complain that the app doesn't show any data after having been installed (it creates the database on first startup). I will be sure to keep you updated if I find any indications to the cause.
