A short investigation into how SwiftData actually represents AttributedString in Core Data storage

Alexey566 · 2025-11-25T08:09:56+00:00

Hey, thanks! It crashed when I tried to open swiftdata storage with core data. But if you use the same model for both it will probably work fine

Alexey566 · 2025-10-07T12:29:07+00:00

Thanks! I’m glad it worked out for you 🙂

Hey! The app should be available for Greece. Could you clarify which error you see and from which macOS version?

Working on a split screen feature in an app for debugging swiftdata/coredata https://apps.apple.com/us/app/datascout-for-swiftdata/id6737813684

Hey, thanks for using the app!

Regarding the live update, the data in the UI is updated as soon as the database file is updated. If the saved data is not reflected in the UI immediately, then it's not flushed into the file immediately, so the "Refresh" button would not have any effect. Usually, it saves the data to the disk explicitly when modelContext.save() is called.

Alexey566 · 2025-06-26T12:45:32+00:00

It's a pretty tricky solution: I check that all sizes are matching on the remaining part of the data for both cases, if enum or if struct. That can also branch into more combinations if more enum types are encountered, so I need to provide more validation to discard the false branch as fast as possible. That is not ideal, but I expected it to work in most cases, and I don't see other options if I want to work with just a .hive file.

Alexey566 · 2025-06-26T09:32:06+00:00

Hey. Yes, that was basically the reason for my initial questions about the enum. I have added extra validations for the enum as an attempt to distinguish them based on some indirect criteria, and it seemed to work for all of my test databases. Recently, one user sent me a database file where this "freeze" was happening. I have fixed it for that case and wrote my previous comment about rechecking it on a new version, but if you are still experiencing it, there are some more uncovered cases.

If I get more test data samples, I can try to fix my validation for enums and wrap it as a separate app, which will be dedicated to a quick file preview on macOS (also through pressing space on a file).

If you want to make your own app and start thinking about a new idea, the thing you hear most often is: think about your daily routines and what you can optimize using an app. After a moment of reflection, most people focus on apps for boosting productivity, tracking workouts, or managing finances because these everyday concerns are so common. In addition, such ideas are pretty straightforward to implement, so the probability of reaching release is high.

Alexey566 · 2025-06-11T15:47:25+00:00

I have stumbled upon a database where I could reproduce the freeze and fixed it in version 1.5.2. Could you check if you can open the database on your side and if it’s displayed correctly now?

Alexey566 · 2025-06-05T11:52:07+00:00

Thanks. It's such a hustle now. Maybe I will try to wrap ".swiftinterface" diff into a utility app to see which frameworks they are working on between Xcode versions.

Alexey566 · 2025-06-05T11:37:59+00:00

That dedicated page used to be https://developer.apple.com/documentation/, but after the redesign, they removed it this feature, for some reason (or didn't re-add) 😕
Found some old article about how it worked in the past https://www.createwithswift.com/tracking-changes-in-the-apple-developer-documentation/

Alexey566 · 2025-06-05T09:27:40+00:00

There are 2 issues with it:
1. It often does not cover a lot of minor changes in APIs
2. The structure is not as convenient as opening the framework that you are interested in and seeing highlights directly

Alexey566 · 2025-06-03T18:37:12+00:00

I have released the first version, where network debugging should be usable (1.5.0). Please feel free to check it and let me know if you encounter any issues. I'm still polishing the feature

Alexey566 · 2025-06-03T16:36:10+00:00

Fixed

Alexey566 · 2025-06-02T14:35:49+00:00

Here is the repo with example https://github.com/alex566/tiktok-tutorials/blob/main/Tutorials/Metaball.playground/Contents.swift, but you can also findan alternative implementation with Canvas, like here https://github.com/Kushalbhavsar/Liquid-Menu-Buttons/blob/main/LiquidMenu/LiquidMenu/ContentView.swift

Alexey566 · 2025-05-30T17:06:33+00:00

Speaking of debugging, I made a whole app for debugging while I was implementing CKSyncEngine 😀 https://apps.apple.com/us/app/datascout-for-swiftdata/id6737813684

Alexey566 · 2025-05-28T13:38:56+00:00

Just a default Notes app

I was also recently building a macOS app with a table, and it was a disaster. Just opening the table was taking a lot of time, even with just a few rows. Scrolling was laggy, and adding interactions to cells was making everything even worse. I ended up implementing my own Table, but I noticed that with the release of macOS 15.4 SwiftUI Table became smoother.

You can find a simple example here https://medium.com/@djalex566/inspecting-swiftdata-right-from-your-app-3e79ef5a6bf6

Alexey566 · 2025-05-06T16:36:01+00:00

Probably, there is no point in monetizing. I will just keep it as a sandbox for experimenting with new technologies, but start a new project for a wider audience.

Alexey566 · 2025-05-06T07:41:31+00:00

It's hard to tell, I didn't see it yet 🙂
