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 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 begin building the “reminders” part of Apple’s Reminders app, including listing, creating, updating, and deleting them. We will also add persistent filters and sorts, per list, all powered by a complex, dynamic 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.

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.
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.
Due to the amount of discussions that reference @pointfreeco, we added their logo as an emoji in our slack.
Please stop releasing one amazing video after the other! I'm still at Episode 15! #pointfreemarathon #androiddevhere
Watching the key path @pointfreeco episodes, and I am like 🤯🤯🤯. Super cool
Their content pushes the boundary of my knowledge, and it's fun to watch!
Every episode has been amazing on Pointfree, yet somehow, you've managed to make these Parser combinator episodes even better!!! ⭐️⭐️⭐️⭐️⭐️
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.
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 😅
I listened to the first two episodes of @pointfreeco this weekend and it was the best presentation of FP fundamentals I've seen. Very thoughtful layout and progression of the material and motivations behind each introduced concept. Looking forward to watching the rest!
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!
