these are the only instances of the string “keyPath” that I can find in the project, and searching through both Swift and Apple documentation I can’t figure out what it means to have a “#” before a function name.
@pavedwalden You use #keyPath() to create key paths that are checked at compile time instead of using raw strings which may crash at runtime. This improves both key value coding and observing mechanisms used by Core Data under the hood.

Please let me know if you have any other questions or more issues about the whole thing when you get a chance. Thank you!
