Totally understand that this is an advanced course and is therefore for advanced users, but I would have really appreciated a small background on the C functions I was trying to implement before throwing me into the challenge. Even after digging into the man pages for all of the hint functions I was still very confused as to what I was supposed to be doing. I don’t think I have done C file I/Oish stuff since college 🙂.

Thanks for the feedback. Something I will take into account next time around.

Felt a lil lost in the challenge due to a lack of knowledge of the setup of the File.swift file and what it was meant to do. As mentioned by the other user, I would love to redo this challenge with something a lil simpler or even some additional intro to the setup of this project. Thanks!
