The Day 15 Lesson is an introduction to all of the ways you can save data and covers the basic File System access.
There's a lot of cool technologies like Core Data, CloudKit, and app backends. Before you use those, I think it's important to understand how saving files works, and how you can make sure your code is working correctly.
I'm preparing two lectures and a bunch of code tutorials that will feed into the code exercise. I'm also including a ton of links for additional resources if you want to dig into one of the related, more advanced file saving technologies. (Look under the video on the website)
