If you’ve built modals or alerts in SwiftUI, chances are high you started with the classic .alert(“Title”, isPresented: $isShowingAlert). It’s the default approach shown in most basic tutorials. However, as soon as your alert needs to display dynamic data or work with isolated Core Data child contexts and draft objects, the isPresented pattern quickly Read more
If you’ve spent any time working across different programming languages, you’ve likely encountered two distinct design philosophies for object creation: When designing Swift APIs—whether for an app architecture or an open-source library—a common question arises: Should you write a make…() factory method or a convenience init? The short answer: Swift strongly prefers initializers. Let’s break Read more
If you work with Xcode long enough, your local development environment inevitably collects digital dust. Every major Xcode update, beta cycle, or iOS SDK transition leaves behind orphaned, “unavailable” simulator targets that clutter your disk space and muddy your tooling outputs. Running xcrun simctl list might show dozens of ghost devices tied Read more
If you have ever built an editing flow in SwiftUI, you know the classic requirement: Changes should only commit when the user explicitly hits “Done.” If they hit “Cancel,” any experimental property modifications should instantly vanish. In Core Data, developers used nested child contexts to stage edits. In SwiftData, direct equivalents to Read more
If you’ve spent enough time building complex forms driven by optional data structures, like a Core Data staging context or a CloudKit configuration schema, you have likely run headfirst into a frustrating race condition. You have a dynamic form row that toggles open when data exists, and a clear button Read more
Introduction SwiftData’s @Query is often treated as a “black box” that just works. But what happens when the underlying SQLite store becomes unreachable, or a schema mismatch occurs mid-session? Unlike traditional data-fetching patterns that return an optional or a Result type, @Query is designed for UI Stability. 1. The Resilience Rule The most important thing to understand Read more
If you were a SwiftUI developer in the summer of 2023, you remember the feeling. WWDC had just dropped. The heavens opened, and out came the Observation Framework. We were told to delete our ObservableObject protocols, throw @Published in the bin, and embrace the clean, macro-powered future of @Observable. But then, iOS 17 Beta 5 happened. And it Read more
Building a library is rarely a straight line. It’s a series of “What if?” moments followed by “Oh, that’s why…” realisations. When I set out to build Swift Streamable Actors, the goal was simple: make Actor state observable via AsyncStream without the boilerplate. But getting there required navigating the strict world of Read more
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
