#25 Network Caching 23:33

We come back to our unfinished Swift Talk iOS app and implement a lightweight network cache for offline support. We keep our networking code from episode #1 untouched to maintain a clear separation of concerns.

#11 Evaluating Expressions 29:36

We write an evaluator for a simple expression language. We write our code in a test-driven way, which saves us time and helps us verify the correctness the code.

#5 Connecting View Controllers 20:14

We refactor our code by moving the app's flow from the storyboard into a separate class. Our goal is to manage the view controller flow from a central place so that view controllers don't have implicit knowledge of their context.
