Default CoreData error message is cryptic #60
Description
Take a version of a SwitchList layout file intended for a later version of
SwitchList, and run with an earlier version. You'll get an error like:
"Persistent store migration failed, missing source managed object model."
That's way too cryptic; adding a more human message would be much more helpful.
There's been one case of this happening to an actual SwitchList user.
