Thank you so much for your help! I've done a bit of research and I think I understand it all now! Correct me if I'm wrong, but I've learnt that theres a Data Container within the App's sandbox which holds, among other things, a Library directory. This Library directory has a cache section and an Application Support section, and the Application Support section gives the App the ability to mark certain files for iCloud or iTunes backups. Great to know! Thanks a ton for your help!

Thank you for your response! I read that in a reply to a question posted on Stack Overflow. It was the answer to the question with the most votes so I figured it was correct, however I just noticed that all the other answers mentioned that that particular answer was wrong 😂. So would I need to store that .CVS file in the documents directory? Or can I keep it in the folder with the rest of the App's utilities? Sorry if this is a simple question, this is my first app. Thanks!
