#56 Binary Search Trees 27:00

In this episode, we implement a binary search tree as an alternative to the sorted array from the last episode. We benchmark the performance of insertion and lookup in both data structures, with some surprising results.

#49 Deep Linking at Kickstarter 27:11

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.

#65 Playground QuickLook for Binary Trees 27:58

We create a custom Quick Look extension to visualize binary tree structures in playgrounds.

#67 Reactive Data Structures: Linked Lists 25:58

We build a reactive linked list on top of reactive programming primitives. We implement a reduce method on this type, which does the minimum amount of work when the underlying data changes.

#58 Red-Black Trees 31:51

Building on the binary search tree code from episode #56, we implement red-black trees as self-balancing tree data structures and benchmark their performance.

#45 Server-Side Swift: Routing 22:47

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.

#7 Stack Views with Enums 21:43

Stack Views are great for prototyping. To make them even easier to set up in code, we create an abstraction using enums to specify UI elements in a declarative style.

#62 Testable View Controllers with Reducers 31:00

We show how the reducer pattern can be used to make typical view controller code more testable.
