I had the same issue. I started fresh again from episode 29, created the new model v.1, changed name to fullName, updated the RenamingID to 'name', and changed the 3 occurrences in the code from name to fullName. Each time the Xcode would crash and I would get the same errors above. I cleaned the derived data and the cleaned the build folder but still nothing.
The only way I was able to get it to work was when the Simulator was up, go into the Hardware menu, then select Erase All Content and Settings. Let me know if that works for you.
