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.

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?

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!
See you then!
This week we show how we can push our app’s validation logic to the *database* using triggers. This ensures data integrity no matter what feature is interacting with the backend database.

Episode #332: Persistence Callbacks: Validation Triggers
We add a new tag editing feature to our rewrite of Apple’s Reminders app to show how we can use database triggers to validate them, and prevent invalid state from ever entering our user’s data.

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 👀
