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.

SQLite is one of the most well-crafted, battle-tested, widely-deployed pieces of software in history, and it’s a great fit for apps with more complex persistence needs than user defaults or a JSON file. This collection serves as an introduction to the basics of SQLite, as well as an exploration into more advanced topics and techniques for integrating SQLite into your applications.
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?
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.
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.
We have this thing called WWTV at #PlanGrid where we mostly just listen to @mbrandonw and @stephencelis talk about functions.
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!
So many concepts presented at #WWDC19 reminded me of @pointfreeco video series. 👏👏 So happy I watched it before coming to San Jose.
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
tfw you are excited for a 4 hour train ride because you'll have time to watch the new @pointfreeco episode 🤓🏔🚂 #MathInTheAlps #typehype
@pointfreeco ❤️: Thank you! 🧠: … The brain can’t say anything. It is blown away (🤯)!
Watching the key path @pointfreeco episodes, and I am like 🤯🤯🤯. Super cool
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!
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.
