We will take a new approach inspired by Gary Bernhardt's "functional core, imperative shell" pattern that we like to call "nonisolated core, isolated shell."

Let's explore how we achieve this sendability in ComposableArchitecture 1.0, why it's not ideal, and how a few new Swift concurrency tools allow us to get closer to our goal in a better way.

We will be building the reimagined ComposableArchitecture store from scratch and show all the benefits that come out of strictly controlling isolation through every layer of the library.

Every once in awhile we release a new video free for all to see, and today is that day!
