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 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.
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.
What are the best, modern practices for persisting your application’s state? We explore the topic by rebuilding Apple’s Reminders app from scratch using SQLite, the most widely deployed database in all software. We will dive into many of SQL’s most powerful features, such as foreign keys, triggers, common table expressions, and more.
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.
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.
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.
This is surely one of the best shows for Swift folks out there! The content and explanation is at a really high bar!
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... 😮
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
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.
Honestly, I'm an Android developer, I write applications in Kotlin. My colleague iOS developer told me about your course. And I liked it so I decided to buy a subscription.
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!
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 😅
Please stop releasing one amazing video after the other! I'm still at Episode 15! #pointfreemarathon #androiddevhere
Really love this episode - thanks @mbrandonw + @stephencelis! Understanding Swift types in terms of algebraic data types is such an elegant way of seeing the # of possible values your Swift types will represent 🤯 #Simplifyallthethings #GoodbyeComplexity
