Expert guidance, battle-tested open source tools, advanced AI skills, exclusive videos, and a community of likeminded engineers.
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.
It’s time to go beyond the basics with a deep exploration of isolation, noncopyable, and nonescapable types. But before we get into all the nitty gritty details we will demonstrate why understanding these topics matters, starting with a preview of isolation in Composable Architecture 2.0.
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!
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.
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.
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.
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.
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 (🤯)!
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!
Please stop releasing one amazing video after the other! I'm still at Episode 15! #pointfreemarathon #androiddevhere
My new favourite morning routine is feeding 👶🏻 while watching @pointfreeco
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... 😮
Their content pushes the boundary of my knowledge, and it's fun to watch!
This is surely one of the best shows for Swift folks out there! The content and explanation is at a really high bar!
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!
