I am on page 185 of the PDF version of the Checklists Tutorial. Everything seems to be saving and loading fine, but I noticed that if I switch to a different device in the simulator, then the saved data does not appear. Right now, I am not testing on any real devices. Why does the data not appear when I switch devices in the simulator?
All simulator devices have their own file structure. They are treated as completely different devices, just as if you would have two different iPhones.
