I made some slight modifications to your prompt and got something working: Here's the prompt: https://i.imgur.com/lUjLTsd.png https://i.imgur.com/lUjLTsd.png Plain text: https://pastebin.com/HTUjcy7M https://pastebin.com/HTUjcy7M The two differences from your prompt are I changed "A listing of horses" to "A listing of horses that the user has added" and at the end I added "Use NSUserDefault for data persistence, not coredata". I'm modifying the model prompt as something like that should definitely not be needed in the app specifications.
