We use Xcode's memory debugger to resolve all the reference cycles in our glitch-free reactive code and introduce a proper ownership model.

Episode 81 · Dec 22 2017

We refactor the simple reactive library from the last episode using topological sorting to avoid any temporarily wrong values.

Episode 77 · Nov 24 2017

We look at an example of a reactive pipeline with surprising behavior, discuss why it occurs, and how it could be improved.

Episode 76 · Nov 17 2017

We use the reactive array type from episodes #67 and #69 to back a table view. This allows us to correctly animate changes in the underlying data, even with filter and sort transformations applied.

Episode 70 · Oct 06 2017

We build a reactive array type on top of the reactive list from episode #67 and implement a filter method.

Episode 69 · Sep 29 2017

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.

Episode 67 · Sep 15 2017

Lisa from Kickstarter shows us their test-driven development process to reactive programming.

Episode 53 · Jun 09 2017

We make our Signal implementation thread-safe by safeguarding the access to shared resources.

Episode 42 · Mar 24 2017

We add the ability to map over signals and control subscriptions in a more fine-grained manner. Along the way, we improve the signal ownership model and implement the concept of disposables.

Episode 40 · Mar 10 2017

We extend the Future type of a previous episode to a simple reactive library. Along the way, we dive into debugging a reference cycle in our implementation.

Episode 39 · Mar 03 2017

We implement a Futures type that we can use instead of callbacks as a first step towards a reactive library.

Episode 36 · Feb 10 2017

We take a look at how reactive programming challenges us to think differently.
