That is expected behavior. The "tildefied" document, as I call it (tilde = "~") is in fact the old document, prior to migration, which Core Data has renamed. It is an undocumented "feature" of Core Data. Apparently, the idea is that, with help from your Support Department, a distressed user can revert if the migration gave undesired results.
So it looks like your SQLite migration is working correctly. Only your XML migration is failing.
