We extend the networking code from the first episode to support POST requests. Besides using Swift's enums with associated values and generics, we get to implement a map function on a custom data type.
In this episode, we implement search functionality for our Ledger GUI app. In the process, we leverage several aspects we've talked about before, such as connecting view controllers, managing application state, and parsing user input.
We build the basic routing infrastructure to map paths to the code that should handle a particular request. We take a different approach than most web frameworks in an attempt to make the code type safe and more at home in Swift.
Brandon from Kickstarter joins us to discuss deep linking into an iOS app. We show how to unify all potential entry points into the app using a common route enum, and then we take a look at this pattern in Kickstarter's open source codebase.
