Let's dial up the complexity of our Wasm application! We'll introduce some async logic in the form of a network request. We'll take steps to not only control this dependency, but we'll do so across both Apple and Wasm platforms, and we'll isolate its interface from its live implementation to speed up our builds and reduce our app's size.

We are going to take a Swift feature _into the browser_. We will set up a WebAssembly application from scratch, show how to run and debug it, and even set up some basic UI. And then we will integrate our existing model into it, all powered by the magic of Swift's Observation framework.

It's time to go cross-platform! We will take a feature written in Swift and use it in vastly different situations, including not only SwiftUI and UIKit, but beyond Apple's frameworks and ecosystems. We will start with a baby step and introduce our feature to a third party view paradigm, Airbnb's Epoxy.

While we rebuilt SwiftUI bindings in UIKit to power state-driven navigation, that's not all SwiftUI uses them for! Let's see what it takes to power `UIControl`s from model bindings. And finally, let's ask "what’s the point?” by comparing the tools we’ve built over many episodes with the alternative.

We round out our stack navigation tools with support for an `@Environment`-like feature for holding onto the stack's path, a `NavigationLink`-like feature for pushing features onto the stack from anywhere, and we'll handle every corner case from deep-linking to user dismissal.

We have now implemented tree-based navigation in UIKit, driven by the Observation framework, but there is another form of navigation to think about: stack-based navigation, where you drive your navigation from a flat collection of states rather than a heavily-nested type. Let's leverage Observation to build a really nice tool for stack-based navigation.

While SwiftUI bindings were almost the perfect tool for UIKit navigation, they unfortunately hide some crucial information that we need to build out our tools. But never fear, we can rebuild them from scratch! Let's build `@Binding` and `@Bindable` from scratch to see how they work, and we will use them to drive concise, tree-based navigation using enums.

We have built the foundation of powerful new UIKit navigation tools, but they're not quite finished. Let's improve these APIs to handle dismissal by leveraging another SwiftUI tool: bindings. We will see how SwiftUI bindings are (almost) the perfect tool for UIKit navigation, and we will see where they fall short.

Now that we have a tool that brings the power of the Observation framework to UIKit, let's put it through the paces. We will use it to build state-driven navigation tools that can drive alerts, sheets, popovers, drill-downs, and more, and they will look a lot like SwiftUI's navigation tools.
