Over the years we have described many advanced topics to better support the complexities of your app (domain modeling, composition, dependencies, testability, and more!).

And now we are distilling that into a collection of docs that can seed the context of your AI editor!

One of our favorite series is “Back to basics: Equatable and Hashable.”

We explain the mathematical foundations of these protocols, and show that deviating from their semantics will introduce subtle bugs in our apps.

This is just a lovely api, turning swift strongly typed APIs into safe SQL queries:

Nice, good you got unblocked! If you found success with that project I’d recommend having a wee look at The Composable Architecture by PointFree too 👌

Hey! Good to hear from you mate, sorry I'm so slow at replying. Don't check this much. Did you figure this out in the end? I wouldn't say that it's a singleton, more a difference in how SwiftUI treats sources of truth. I've not found much success in contorting SwiftUI to work with MVVM personally.

Similar experience here. On a 16 Pro, and the whole OS feels sluggish and janky in places. Hoping it gets better in future releases. The only reason I upgraded from my 12 Mini was for the battery life.

The best part of our SQLite + CloudKit synchronization tools is that they work seamlessly behind the scenes without you having to think about it.

But, we don't hide the CloudKit metadata from you. It is possible to query for your CKRecords and CKShares directly from SQL!

Now that our SQLite + CloudKit public beta is out we can explain why we spent 4 weeks diving deep into SQL triggers.

They are the primary tool we use to implement synchronization. They allow us to listen to everything happening in your database so that we can replay those changes to CloudKit.

It may seem too good to be true, but with just these few lines of code you will be able to generate an iCloud link that can be shared with others for collaboration on a record (and its associations).

So, sharing a reminders list also shares all of its associated reminders. 🤯

This is wild. How is it able to do it in real time when flagship LLMs take several seconds to generate text? I assume not LLMs (world generation isn’t really language), but then why are LLMs so (relatively) slow?

Perception 2.0: An updated back-port of Swift’s Observation framework We are proud to announce Perception 2.0: A full back-port of Swift’s Observation framework that works on iOS 13+ and macOS 10.15, and now includes the newest tools from the framework, including Observ...

Have you heard about the new Observations tool coming to Swift 6.2? Did you know that it is unfortunately limited to iOS 26+?

Well, luckily we've just back ported it to our Perception library so that you can use it in iOS 13+ and Xcode 16+:

Next week we will push things even *further* by calling Swift code *from* SQLite! We will use these database callbacks to improve the ergonomics of our rewrite of Apple’s Reminders app.

See you then!

Introducing swift-erlang-actor-system I'm excited to share a new actor system we've been building for Swift's distributed actors: swift-erlang-actor-system. This actor system enables Swift programs to join a distributed Erlang cluster. ...

More progress around Erlang/Swift interoperability

This week we finished our popular “modern persistence” series. This gives you a deep understanding how to model your domains, migrate SQL databases, run complex queries, insert/update/delete data, and write tests!

And this sets up for more advanced topics we have coming soon 👀

iPad got some _serious_ love this year!

Tabs in the Photos app are back. This might be the greatest thing Apple have ever done. Up there with giving us a physical escape key back.

Happy WWDC keynote day to all who celebrate! Wasn’t sure how I’d feel on the day, but so far it’s mainly been excitement 🤩

Another recommendation for face pulls here - just generally a great move for upper back.
