Point-Free is a video series exploring advanced topics in the Swift programming language, hosted by industry experts, Brandon and Stephen.
We continue our series on “modern persistence” with an important topic: “callbacks.” Callbacks are little hooks into the lifecycle of your data model so that you can be notified or take action when something changes. We will first explore the “Active Record” pattern of callbacks, popularized by Ruby on Rails, and then see how we can improve upon them.
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.
SQLite’s full-text search capabilities come with many bells and whistles, including support for highlighting search term matches in your UI, as well as generating snippets for where matches appear in a larger corpus. We will take these APIs for a spin and enhance our Reminders search UI.
We’re ready to take advantage of some of the superpowers of full-text search, starting with relevancy. We will do a deep dive into the ranking algorithm of SQLite’s FTS5 module, explore how the text of a document affects its relevancy score, and how we can tweak these scores based on the column containing a match.
We start to leverage SQLite’s built-in full-text search capabilities to power our feature. We learn about virtual tables, create one that stores the searchable data, populate it with the help of database triggers, and show just how powerful and succinct search can be.
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.

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.
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.
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.
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!
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.
I bought the annual subscription and after I watched all videos and played with the sample code and libraries I can say it was the best money I spent in the last 12 months.
Due to the amount of discussions that reference @pointfreeco, we added their logo as an emoji in our slack.
So many concepts presented at #WWDC19 reminded me of @pointfreeco video series. 👏👏 So happy I watched it before coming to San Jose.
Thanks @mbrandonw @stephencelis for the very pedagogical series with @pointfreeco Excited and looking forward to learn from the series
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
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.
Honestly, I'm an Android developer, I write applications in Kotlin. My colleague iOS developer told me about your course. And I liked it so I decided to buy a subscription.
