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!

Episode 315 • Mar 3, 2025

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.

Last week we released SharingGRDB, an alternative to SwiftData powered by SQLite, but there are a few improvements we could make. Let’s take a look at some problems with the current tools before giving a sneak peek at the solution: a powerful new query building library that leverages many advanced Swift features that we will soon build from scratch.

Episode 328 • Jun 16, 2025

We conclude our series on “modern persistence” with advanced queries that leverage reusable SQL builders, “safe” SQL strings, and complex aggregations, including JSON arrays and a query that selects many stats in a single query.

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.

SwiftUI

Collection

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.

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.

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.

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

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

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!

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

Every episode has been amazing on Pointfree, yet somehow, you've managed to make these Parser combinator episodes even better!!! ⭐️⭐️⭐️⭐️⭐️
