Point-Free is a video series exploring advanced topics in the Swift programming language, hosted by industry experts, Brandon and Stephen.
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!
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.
Last week we released SharingGRDB, an alternative to SwiftData powered by SQLite, but there are a few improvements we could make. Let’s take a look at some problems with the current tools before giving a sneak peek at the solution: a powerful new query building library that leverages many advanced Swift features that we will soon build from scratch.
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.
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.
We conclude our series on “modern persistence” with advanced queries that leverage reusable SQL builders, “safe” SQL strings, and complex aggregations, including JSON arrays and a query that selects many stats in a single query.
We dissect some of the most important and interesting topics in Swift programming frequently, and deliver them straight to your inbox.
We cover both abstract ideas and practical concepts you can start using in your code base immediately.
Download a fully-functioning Swift playground from the episode so you can experiment with the concepts discussed.

Swift has many tools for concurrency, including threads, operation queues, dispatch queues, Combine and now first class tools built directly into the language. We start from the beginning to understand what the past tools excelled at and where they faultered in order to see why the new tools are so incredible.
The Swift language has grown over the years and become more and more powerful. It now boosts a comprehensive static type system (generics, existentials…), a suite of concurrency tools (actors, dynamic isolation…), and most recently even ownership capabilities (consuming, borrowing, non-copyable types…). In “Back to basics” we will focus on just one part of the language in order to uncover the deep theory behind that feature as well as provide concrete advice for writing real-world code.
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?
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.
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.
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.
@pointfreeco ❤️: Thank you! 🧠: … The brain can’t say anything. It is blown away (🤯)!
My new favourite morning routine is feeding 👶🏻 while watching @pointfreeco
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
Due to the amount of discussions that reference @pointfreeco, we added their logo as an emoji in our slack.
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!
I bought the annual subscription and after I watched all videos and played with the sample code and libraries I can say it was the best money I spent in the last 12 months.
Thanks @mbrandonw @stephencelis for the very pedagogical series with @pointfreeco Excited and looking forward to learn from the series
Every episode has been amazing on Pointfree, yet somehow, you've managed to make these Parser combinator episodes even better!!! ⭐️⭐️⭐️⭐️⭐️
Just became a subscriber! I'm binge watching episodes now! Great content! I'm learning so much from you guys. The repo for the site is the best go-to reference for a well done project and swift-web is something I am definitely going to use in my projects. Thanks for everything!
