Episode #330: Persistence Callbacks: Triggers
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 so...
www.pointfree.co
This week we gave a brief overview of the concept of "callbacks" in databases, which Rails popularized and many other frameworks adopted.
They allow you to execute little bits of logic when a row is inserted/updated/deleted in your database.

SQL “views” allow you to package up a complex query into an entity that can then be queried as if it were a table in its own right. This is an amazing tool for hiding complex queries behind simple interfaces.

This week we display participant information in shared records, all without touching iCloud and instead by leveraging SQLiteData’s metadata. Along the way we will explore two powerful tools to simplify our app: database “views” and the @DatabaseFunction macro.

Once you configure SQLiteData to synchronize to iCloud, you never have to think about it again. You can build new features and let SQLiteData worry about making sure all data is properly synchronized across your users’ devices.

No matter how much love you put into your app, if you store data only locally, the first feedback you will get from users is wanting their data sync'd to all devices, and wanting to share data with friends and family.
SQLiteData makes this possible in just a few lines of code.

CloudKit's APIs are not built on SQLite, but we store its metadata in a SQLite database so it's possible to query for your data and iCloud metadata at the same time. This brings extraordinary powers to your app and we show it off in this week's episode:

This generic property transforms a Binding into a Binding so that you can drive navigation with optional state instead of booleans. This fixes a flawed SwiftUI API for displaying alerts.

Have you noticed that SwiftUI’s alert API is strange? It takes a Binding<Bool> *and* an optional value. What happens when true and nil are provided? Or false and some data??
Luckily it's easy to derive a Binding<Bool> from a Binding<T?> to keep your domain concisely modeled. 👇

This week we showed that secretly SQLiteData manages a database right next to your database for storing metadata associated with iCloud synchronization. And the best part? It’s made publicly available to you so that you can even query it from SQLite!
