I keep getting this error when trying to migrate a sql store:
-[Document configurePersistentStoreCoordinatorForURL:ofType:modelConfiguration:storeOptions:error:] Error NSCocoaErrorDomain 134110 {
NSUnderlyingException = "I/O error for database at /Users/mlink/Desktop/Untitled.db.new. SQLite error code:1, 'no such table: _T_ZEVENT'";
destinationURL = "file://localhost/Users/mlink/Desktop/Untitled.db.new";
reason = "Cannot migrate store in-place";
sourceURL = "file://localhost/Users/mlink/Desktop/Untitled.db";
}
This migration is using the default mapping model created in Xcode. The Event entity was changed to have an abstract parent entity, before it stood alone.
I tried creating an entity migration policy subclass but none of its methods are called. Anyone have any ideas what the problem might be?
