To bring some clearity to what's happening as I work with Core Data, I DL the free SQLLite Database Browser (SQLDBB). It worked fine to copy the db from the iOS simulators Documentsfolder into my desktop and then open it and browse db content just fine in SQLDBB.
BUT
Since the simulator library files are hidden in OSX Mountain Lion by default, I can't use the normal SQLDBBs Open-file dialog to open it.
The file is here in my Mountain Lion Finder (used Finder > Go > "Go to folder" to get it);
~/Library/Application Support/iPhone Simulator/5.1/Applications/...aAppIDnr.../Documents/DataStore.sql
Any suggestions to open it directly in SQLDBB?
