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.

We build a bunch of triggers in a schema-safe, type-safe way using APIs from the StructuredQueries library, including a callback that ensures the Reminders app always has at least one list, and a callback that helps us support drag–drop positional ordering of lists.

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.

We go live with our viewers to unveil our vision for modern persistence. We show just how easy it is to seamlessly synchronize your app's data across many devices, including sharing data with other iCloud users, and we answer your questions.

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.

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 begin building the "reminders" part of Apple's Reminders app, including listing, creating, updating, and deleting them. We will also add persistent filters and sorts, per list, all powered by a complex, dynamic query.

We flesh out the reminders lists feature using advanced queries that aggregate reminders counts and bundle results up into a custom type _via_ the `@Selection` macro. And we show how "drafts"—a unique feature of StructuredQueries—allow us to create and update values using the same view, all without sacrificing the preciseness of our domain model.

We tackle the first screen in our Reminders app rewrite: the reminders lists view. We will take the `@FetchAll` property wrapper for a spin, which is like SwiftData's `@Query` macro, but unlike `@Query` it can be used from both the view _and_ observable models. And we will even get some end-to-end, snapshot test coverage of our feature in place.

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 start by designing the schema that models our domain.
