We conform our CRDT sequence to multiple collection protocols and use it for syncing a simple to-do app.

Episode 301 · Apr 22

We add the ability to delete elements from our CRDT sequence and test the behavior for correctness.

Episode 300 · Apr 15

We change the backing storage of our CRDT sequence from a tree to an array for efficiency.

Episode 299 · Apr 08

We implement and test the merge algorithm for our tree-backed sequence data type.

Episode 298 · Apr 01

We start building a replicated sequence data type, modeling the sequence as a tree.

Episode 297 · Mar 25

After adding more testing to our CRDTs, we integrate them into a small app.

Episode 296 · Mar 18

We implement our second CRDT, a grow-only counter type, and test its behavior.

Episode 295 · Mar 11

We begin to investigate Conflict-Free Replicated Data Types as a way to sync data across devices.

Episode 294 · Mar 04

We implement a property wrapper to access values from our environment.

Episode 277 · Oct 22 2021

We add support for loops to our rule builder, and we implement a basic template infrastructure.

Episode 276 · Oct 15 2021

We implement a result builder that enables us to compose rules similar to SwiftUI views.

Episode 275 · Oct 08 2021

We mimic SwiftUI's environment design to pass values down the site rule hierarchy.

Episode 274 · Oct 01 2021

We show how we replaced our outdated Ruby website with a SwiftUI-inspired static site generator.

Episode 273 · Sep 24 2021

We switch to a bottom-up approach to render trees in a compact but symmetric fashion.

Episode 224 · Oct 09 2020

We experiment with different tree-drawing algorithms to produce readable and compact binary trees.

Episode 223 · Oct 02 2020

We combine the logic for parsing 64-byte chunks from the last episode to process entire files.

Episode 172 · Oct 04 2019

We experiment with porting the low-level approach of a super-fast JSON parsing library to Swift.

Episode 171 · Sep 27 2019

In our 100th episode we take questions from our viewers!

Episode 100 · May 12 2018

We continue to expand our experimental view binding mechanism to implement dark mode in our app.

Episode 74 · Nov 03 2017

We experiment with reactive view bindings that don't rely on runtime programming.

Episode 73 · Oct 27 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

We refine the observation capabilities of our new data type.

Episode 63 · Aug 18 2017

We recap the tradeoffs between classes and structs and start implementation of our new type, leveraging Swift 4's keypaths.
