 modern, best practices for SwiftUI development. We faithfully recreate the Scrumdinger, but with
 some key additions:
 
- 1. Identifiers are made type safe using our [Tagged library][tagged-gh]. This prevents us from
-    writing non-sensical code, such as comparing a `SyncUp.ID` to a `Attendee.ID`.
- 2. Instead of using bare arrays in feature logic we use an "identified" array from our
-    [IdentifiedCollections][identified-collections-gh] library. This allows you to read and modify
-    elements of the collection via their ID rather than positional index, which can be error prone
-    and lead to bugs or crashes.

     it possible to deep link into any screen of the app by just constructing a piece of state and
     handing it off to SwiftUI.
- 4. Further, each view represents its navigation destinations as a single enum, which gives us

+    same time. This cannot be accomplished with default SwiftUI tools, but can be done with our 
+    [SwiftNavigation library][swift-nav-gh].
+ 1. Persistence is handled by our [Sharing][sharing-gh] library, which allows one to hold onto 
+    shared state in an observable model or view, and under the hood any changes to the state will be
+    persisted to external storage, such as the file system. Even the global navigation is persisted

+ 1. All side effects are controlled. This includes access to the file system for persistence, access
     to time-based asynchrony for timers, access to speech recognition APIs, and even the creation
     of dates and UUIDs. This allows us to run our application in specific execution contexts, which
     is very useful in tests and Xcode previews. We accomplish this using our
     [Dependencies][dependencies-gh] library.
