// All the complexity needed to avoid this code probably isn't worth it in the majority of cases.
// Particularly note that the data model doesn't 100% line up with the JSON (some keys have
// slightly different names for instance). A system flexible enough to handle that (say, something
// like Go's json.Marshal) would be nice, but this code, while slightly tedious, isn't really bad.
// Basically I'm saying that a richer JSON<->Swift system built into stdlib would be nice, but the
// bar is pretty high to go pulling in a helper library.
//
// That said, compare the Go code below, and I think it really is much simpler, and scales much better

What are Migrations

Just like how we use Git to version control source code, we use migrations to manage the state of our database schemas.

I'm not really sure what that means...

Imagine you're working on project with another developer, and you're both tasked with creating a specific part of an event planning application. Let's say you are in charge of creating the Users and your friend is going to create the Events.

Let's say you and your friend divided the work in a way so that neither of you will have to to use each other's code to finish your tasks. While you're working on your part of the application, you only really need to touch the Users table when you are working with the database.
