Expert-crafted AI skill documents for building long-lasting Swift applications.
Design, test, and evolve applications using the same principles, libraries, and techniques we use every day at Point‑Free.
We celebrate 8 years of Point-Free with a live stream! We take our brand new “Point-Free Way” skill documents for a spin by building a Flashcards app powered by SQLiteData, and we give a sneak peek at “Composable Architecture 2.0,” a reimagining of our popular library.
We clean up our test suite and make use of the expectDifference helper, for precisely describing changes to state in an exhaustive fashion. We will then rapidly add test coverage using the forthcoming “Point-Free Way” skills documents. Finally, we will achieve the seemingly impossible by writing a test against iCloud sharing!
SQLiteData is incredibly test-friendly. We will show how to configure a test suite for your data layer, how to seed the database for testing, how to assert against this data as it changes, how to employ expectNoDifference for better debugging over Swift Testing’s #expect macro, and how to control the uuid() function used by SQLite.
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 video so you can experiment with the concepts discussed.

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?
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.
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.
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... 😮
Thanks @mbrandonw @stephencelis for the very pedagogical series with @pointfreeco Excited and looking forward to learn from the series
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.
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!
@pointfreeco ❤️: Thank you! 🧠: … The brain can’t say anything. It is blown away (🤯)!
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!
tfw you are excited for a 4 hour train ride because you'll have time to watch the new @pointfreeco episode 🤓🏔🚂 #MathInTheAlps #typehype
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
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!
