I've spent... wasted the weekend trying to figure out what was wrong with
my code or with Core Data.
The symptom seemed to be that I could create entities in my app, and do a
"Save As..." and everything worked right. but when I then added another entity
or 2, and did a "Save", quit the app and reopened the app with the saved file,
the additions from the "Save" weren't there. After looking at everything in my
data model and managed object context 10 times over, checking state of
registered, inserted and updated objects at every point in the process, it
finally looks like the only real problem is that when I use
migratePersistentStore to migrate my in-memory store to a binary store on disk,
if I'm doing a "Save", which means I'm writing to a file I previously created,
the old file isn't getting overwritten, but the call doesn't return an error.
Was there some setup call I needed to make early on so that the second call
to migratePersistentStore should overwrite the first file?
Shouldn't migratePersistentStore be returning an error to tell me that it
didn't overwrite?
