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!

What to expect

New content regularly

We dissect some of the most important and interesting topics in Swift programming frequently, and deliver them straight to your inbox.

Wide variety of topics

We cover both abstract ideas and practical concepts you can start using in your code base immediately.

Playground downloads

Download a fully-functioning Swift playground from the video so you can experiment with the concepts discussed.

Video transcripts

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.

Macros

Collection

Swift 5.9 brings a powerful new feature to the language: macros. They allow you to implement new functionality into the language as if it was built directly in the language itself. However, they can be tricky to get right, and as such one needs to write an extensive test suite to make sure you have covered all of the subtle and nuanced edge cases that are possible.

Back to basics

Collection

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.

Modern Persistence

Collection

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.

A better way to create SwiftUI bindings

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.

Why you can't use enums in SwiftData

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.

Why you can't use booleans in SwiftData

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.

What people are saying

We have this thing called WWTV at #PlanGrid where we mostly just listen to @mbrandonw and @stephencelis talk about functions.

Oscar Alvarez
@iOjCaR

So many concepts presented at #WWDC19 reminded me of @pointfreeco video series. 👏👏 So happy I watched it before coming to San Jose.

Prakash Rajendran
@dearprakash

Thanks @mbrandonw @stephencelis for the very pedagogical series with @pointfreeco Excited and looking forward to learn from the series

Boris Bielik
@h3sperian

This is surely one of the best shows for Swift folks out there! The content and explanation is at a really high bar!

Ferran Pujol Camins
@ferranpujolca

Their content pushes the boundary of my knowledge, and it's fun to watch!

@rehsals

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 😅

Alejandro Martinez
@alexito4

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.

@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!
