I’m thrilled to announce the official release of Swift Streamable Actors, a new Swift macro library that brings AsyncStream-based reactivity to your Swift Actors. If you’ve ever wished you could observe changes to an actor’s properties as easily as an @Observable object, this library is for you. The Inspiration: Manual Streamable Properties Before diving Read more
After converting a Synology SHR‑1 (mirrored) volume to SHR‑0 (single-disk), you will likely want to expand your storage pool to use the extra capacity of the new disk you originally mirrored with. Here’s a step-by-step guide using SSH and command-line tools to safely resize your volume. Note: This guide assumes you have already converted Read more
If you have a Synology SHR‑1 storage pool “with data protection” and the second disk has already been deactivated, you may notice the RAID still shows as degraded. Currently it isn’t possible in the Storage Manager UI to convert back to a single disk “without data protection”. These steps will help you safely update the Read more
This blog post was written with the assistance of ChatGPT. When integrating UIKit components into SwiftUI using UIViewRepresentable, you might come across the context.environment property. While it looks simple on the surface, it hides a powerful mechanism: environment-driven updates. In this post, we’ll explore what context.environment does, how SwiftUI tracks it, and how it can cause Read more
When I attempt to remove a disk from the AppleRAID JBOD APFS I get the error: Also there is a similar error when trying to add a disk: No size options were set for the volume in the container. And I experimented with setting the reserve and quota but it Read more
To upgrade old Combine code in an ObservableObject that had its lifetime tied to a SwiftUI View using @StateObject we can replace it with .task and since async/await gives us a lifetime like a reference type we can do away with the object altogether. In the Combine version of the Read more
When you mark a class as @Observable you can no longer use didSet because the macro converts it to a computed property, e.g. a simple: When expanded becomes: As you can see test has become a computed property that is a wrapper around a private _test property, a bit like Read more
The built-in @Query does not currently support dynamic changes, instead we can use @DynamicQuery from the SwiftDataX open-source package to achieve it. The query declaration looks like this: By default that will load all Prospect model objects, sorting them by name. If the fetchDescriptor property is later changed and this View is Read more
SwiftUI’s design takes advantage of equality to decide if things should be updated. Measurement (backed by NSMeasurement) has something interesting in its Equatable implementation: This means that 0kg is equal to 0g despite their unit being different. This makes sense for comparing weights but not for using it to decide Read more
Reposted from: https://forums.swift.org/t/how-to-use-observation-to-actually-observe-changes-to-a-property/67591/18 I thought I’d share an example of how I am currently using it. I wanted to make an object that maintains a sorted order of the main model’s objects. I used withObservationTracking to update if either the sort order local to this object is changed or if the particular Read more
