Episode 330 • Jul 7, 2025

We continue our series on “modern persistence” with an important topic: “callbacks.” Callbacks are little hooks into the lifecycle of your data model so that you can be notified or take action when something changes. We will first explore the “Active Record” pattern of callbacks, popularized by Ruby on Rails, and then see how we can improve upon them.

How does our SQL-based solution for persistence compare with modern SwiftData? We put things to the test by rebuilding our complex @FetchAll query using @Model and the @Query macro!

Episode 315 • Mar 3, 2025

We finish a sneak peek of our upcoming Structured Queries library by showing how queries built with the library can be reused and composed together, and how we can replace all of the raw queries in our application with simpler, safer query builders.

With our database migrated, it’s time to take the SyncEngine for a spin to see how it seamlessly synchronizes data to and from iCloud, how it resolves conflicts when records are edited and deleted from multiple devices, and even how records are synchronized from different versions of the application and database schema.

Episode 340 • Oct 6, 2025

We show how to add iCloud synchronization to the persistence layer of an existing SQLite application by using SQLiteData. While SQLiteData’s CloudKit tools can be configured with a single line of code, one must still prepare their database schema to be compatible and durable when it comes to synchronizing across multiple devices and versions.

We round out modern search by diving into FTS5’s query syntax language. We’ll learn how it works, how to escape terms sent directly by the user, and we’ll introduce SwiftUI search tokens that can refine a query by term proximity and tags.

What to expect

New content regularly

We dissect some of the most important and interesting topics in Swift programming frequently, and deliver them straight to your inbox.

Wide variety of topics

We cover both abstract ideas and practical concepts you can start using in your code base immediately.

Playground downloads

Download a fully-functioning Swift playground from the episode so you can experiment with the concepts discussed.

Video transcripts

We transcribe each video by hand so you can search and reference easily. Click on a timestamp to jump directly to that point in the video.

SwiftUI

Collection

SwiftUI is Apple’s declarative successor to UIKit and AppKit, and provides a wonderful set of tools for building applications quickly and effectively. It also provides a wonderful opportunity to explore problems around architecture and composition.

SQLite

Collection

SQLite is one of the most well-crafted, battle-tested, widely-deployed pieces of software in history, and it’s a great fit for apps with more complex persistence needs than user defaults or a JSON file. This collection serves as an introduction to the basics of SQLite, as well as an exploration into more advanced topics and techniques for integrating SQLite into your applications.

UIKit

Collection

SwiftUI may be all the rage these days, but that doesn’t mean you won’t occassionally need to dip your toes into the UIKit waters. Whether it be to access some functionality not yet available in SwiftUI, or for performance reasons (UICollectionView 😍), you will eventually find yourself subclassing UIViewController, and then the question becomes: what is the most modern way to do this?

A better way to create SwiftUI bindings

If you have ever created a binding using the get:set: initializer, you may want to reconsider. Doing so can hurt SwiftUI’s ability to animate your view. Luckily there is a better way. You can leverage @dynamicMemberLookup and subscripts to derive new bindings in a way that allows SwiftUI to propertly track where the binding came from.

Why you can't use enums in SwiftData

SwiftData is not capable of filtering and sorting by raw representable enum properties in models. Predicates and sort descriptors will compile just fine when referencing enum properties, but it will crash at runtime.

Why you can't use booleans in SwiftData

SwiftData is not capable of sorting by boolean properties in models. And if you try to trick SwiftData to allow it, you will encounter runtime crashes.

Their content pushes the boundary of my knowledge, and it's fun to watch!

Watching the key path @pointfreeco episodes, and I am like 🤯🤯🤯. Super cool

Three recent @pointfreeco episodes were so interesting I stayed in the treadmill 3x as long as usual and watched them all in a row! Walking may be challenging later/tomorrow... 😮

So many concepts presented at #WWDC19 reminded me of @pointfreeco video series. 👏👏 So happy I watched it before coming to San Jose.

@ferranpujolca

Through videos you constantly introduce ideas and patterns only to later reformulate them into more general ideas. This is awesome and helped me understand a lot of programming concepts. Well done!

Due to the amount of discussions that reference @pointfreeco, we added their logo as an emoji in our slack.

David Piper
@HeyDaveTheDev

Just finished the mini-series on enum properties by @pointfreeco! They pointed out what’s missing from enums in Swift and used SwiftSyntax to generate code to add the missing parts. Thanks for your work @stephencelis and @mbrandonw! #pointfree

Alejandro Martinez
@alexito4

I really love the dynamics of @pointfreeco. The dance of “this is super nice because…” “yes, BUT….”. they clearly show what’s good, what’s not so good and keep continuously improving.
