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.

Episode 331 • Jul 14, 2025

We build a bunch of triggers in a schema-safe, type-safe way using APIs from the StructuredQueries library, including a callback that ensures the Reminders app always has at least one list, and a callback that helps us support drag–drop positional ordering of lists.

We go live with our viewers to unveil our vision for modern persistence. We show just how easy it is to seamlessly synchronize your app’s data across many devices, including sharing data with other iCloud users, and we answer your questions.

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.

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?

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.

Composable Architecture

Collection

Architecture is a tough problem and there’s no shortage of articles, videos and open source projects attempting to solve the problem once and for all. In this collection we systematically develop an architecture from first principles, with an eye on building something that is composable, modular, testable, and more.

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.

After diving into @pointfreeco series reading Real World Haskell doesn’t seem all that intimidating after all. Major takeaway: the lesser is word “monad” is mentioned the better 😅

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

Maxim Smirnov
@Atimca

The best thing, that happened to me for a while. @mbrandonw and @stephencelis really provide a lot of new information according to #ios development and #functionalprogramming. All info could be used in real production without boring academics.

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... 😮

tfw you are excited for a 4 hour train ride because you'll have time to watch the new @pointfreeco episode 🤓🏔🚂 #MathInTheAlps #typehype

Every episode has been amazing on Pointfree, yet somehow, you've managed to make these Parser combinator episodes even better!!! ⭐️⭐️⭐️⭐️⭐️

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!

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