Even though most of our classes, structs, and other types might have initially been created to solve a very specific problem — over time, we quite often find ourselves wanting to use a highly similar version of that same type or logic, but for something entirely different. This week, let’s take a look at a technique for making that happen — that involves making certain types increasingly configurable.

This week, let's take a look at how we can implement data sources for table and collection views in a more reusable manner, and how doing so can let us make our list-based UI code more composable and easier to work with.
