This can be tricky to get right, and so we take the time to properly handle all of the edge cases ..read more

We need to observe changes to user defaults in order to play those changes back to `@Shared`, and we need to put in a bit of extra work to make everything testable ..read more

But let's take things one step further. Sometimes we want shared state to be local and explicit, but there are other times we want shared state to be ubiquitous throughout our application. Let's beef up our property wrapper to do just that ..read more

We will see how a deeply nested integration of features all sharing the same state can be tested simply, and we will see how we can leverage the same tricks employed by the test store to add debug tools to reducers using shared state ..read more

If you are a Point-Free subscriber you can access your private podcast feed by visiting https://www.pointfree.co/account. --- The `@Shared` property wrapper can effortlessly share state among features to build complex flows quickly, but because it is powered by a reference type, it is not compatible with the Composable Architecture's value-oriented testing tools. Let's address these shortcomings and recover all of the library's testing niceties ..read more

While we have seemingly simplified nearly every inch of the library as it interfaces with SwiftUI, let's zoom out a bit, explore how some integration tests that benchmark certain aspects of the library have changed, and migrate the Todos application we built in the very first tour of this library to the new tools ..read more

With Observation, that all changes. By eliminating view stores and observing store state directly, we are free to totally reimagine bindings in the Composable Architecture, and get rid of even more concepts in the process ..read more
