In the final part of my Rich Notes App series, we’re adding categories, sorting, and filtering with SwiftData plus a few finishing touches to make it shine.

Is there a way to use SwiftData in a view model, with automatic syncing of changes to the saved data, so I don't have to write shit like this because I have data in the model, but must have a `@Query` in the view to get the stored data?

Just published a full walkthrough on building a #SwiftData backed notes app using our rich text editor from part one. We cover models, CRUD, navigation, previews, and how #AattributedString is stored as JSON in SQLite. Give it a watch. youtu.be/SL8yxBGuTuo

I have finally managed to introduce persistence (via SwiftData) to Librarius.

I started by making my data models structs – as Apple recommended – only to find out SwiftData needs classes.

It made sense, so I switched to classes, it was hell on earth. I then, thanks to the advice of a friend, had both classes and struct representations (and class models could be instantiated from structs).

This made life easier, but is it a general pattern?

FB21159411 #CloudKit causes excessive view updates with #SwiftData Queries

Things are pretty bad for me to file feedback.

App views are updated far too often regardless if data changes. (at least on MacOS)

For simple text views you are unlikely to notice. With more complex views such as a map with the markers dancing around with each update it is a deal breaker.

I am wondering if this is causing some sketchy app behavior in Tahoe?

or I'm holding it wrong…

#SwiftUI #Swift

Initial implementation of indexing AppEntities backed by #SwiftData in spotlight - always nice to see an old library making it simpler (FetchDescriptorObserver). https://gist.github.com/juanarzola/131c81f2cdb438dc8114bb003b87eff2

Should be ok for just a few folders. Might need to add paging to the library to make it usable for more copious entities.

It’s kinda fun that you can go from a local app to a multi-platform client/server app using #SwiftUI and #SwiftData with very few changes to your data model and with no changes to the APIs you call

Today's mystery:

https://gist.github.com/juanarzola/c5c2268b88840ec4bc6f0be2a053b2bb

This code is an extension factory method on FetchDescriptor that builds a FetchDescriptor that fetches a #SwiftData model by UUID, if the model conforms to UUIDString.

Works normally. Except when running in within AppIntents (specifically in AppEntity functions that fetch the entities) on Release mode, where the uuid isn't found in the schema of models. Works on Debug.

Solution was to not use the extension, and inline the FetchDescriptor in the fetching function, using the concrete type in FetchDescriptor, instead of Model.

Why? uuid optimized out? Perhaps.

Trying to fetch a SwiftData model filtered by an enum (BookStatus) using #Predicate or Predicate(\.status, equals:) fails every time:
Key path cannot refer to enum case / Cannot infer key path type.
Anyone found a clean way to filter enums in SwiftData?
#iosdev #swift #swiftdata

"I wonder why my sorting/grouping logic breaks when I combine model IDs from freshly-fetched #SwiftData objects with cached IDs"

because gotcha, id identity doesn't survive coding

but don't worry ids, have real ids in them (`id.id`).

such an intuitive API

Starting in under 1 hour!!! SwiftData live 3 hour workshop!!

You will learn about SwiftData architecture, relationships, testing and even CloudKit integration. I will show you the built-in SwiftData architecture, which allows you to separate your domain/business logic from views and easily make it testable.

AI is dumb. Still.

I have a #SwiftData property with `@Attribute(.unique, .spotlight)`. It correctly said that was invalid SwiftData, but incorrectly said it was the `.spotlight` value that was invalid. `.unique` is invalid in SwiftData.

I told it to fix it. It said I was right, and then did the exact same thing again.

Tomorrow I am hosting a 3 hour live hands-on workshop on SwiftData. If you use SwiftData in your apps then this workshop is for you.

You will learn about the SwiftData built-in architecture, relationships, testing and even CloudKit integration.

I will add I've only been debugging this on #macOS as that's where my app I want to use with #CloudKit originates

#SwiftUI #SwiftData

Still debugging overzealous #SwiftUI view redraws when using #SwiftData.

It appears that any time you use a query the view will be redrawn for any CoreData notifications.

For example each time a DB checkpoint is triggered the view redraws regardless if any data has changed.

Those notifications happen very often.

I've created an sample project with a static view and it refreshes constantly, even when the queried data is not used.

Unsure if 26.1 resolves anything.

In my app using SwiftData, I have a `@model` class with relationship to other `@model` classes. I want a property `updated` on the parent class to be updated to `Date.now` any time any property on the parent class or child classes is modified. I cannot find a way to do this. (Using `didSet` on a child class’ attributes doesn't work because the implicit `@_PersistedProperty` macro sets the backing value via key/value encoding so the actual property's property observers don't get called.) How is this so hard?

#Swift #SwiftData

Stop making working with #SwiftData complicated!!

In this workshop, I will demonstrate how you can use the SwiftData built-in architecture to write your apps. You will also learn about relationships, testing and CloudKit integration.
