Issue #1046
Every app that runs on an Apple device must be signed with a certificate. The signature tells the OS that the code comes from a known developer and hasn’t been tampered with. Xcode manages most of this automatically, but …
Issue #1045
Distributing a macOS app outside the App Store requires notarization. Apple scans the app for malicious content and attaches a ticket to it so Gatekeeper can verify it offline. Without notarization, users on macOS 10.15 and later see a …
Issue #1044
Good naming is one of the most underrated forms of documentation. A well-chosen name removes the need for a comment. A poor one forces every reader to mentally re-derive what the code does. Apple’s own frameworks are a rich source …
Issue #1043
iOS 18 introduced interactive controls that live directly in Control Center and on the Lock Screen. Unlike widgets that only display information, control widgets respond to taps, letting users trigger actions without opening the app. A …
Issue #1042
Apple’s Vision framework has quietly grown into one of the most capable on-device ML libraries available on Apple platforms. Starting in iOS 17, it gained the ability to separate the foreground subject from the background of a …
Issue #1041
The Vision framework has provided text recognition since iOS 13 and macOS 10.15. If you have ever needed to extract text from a screenshot, a photo of a receipt, or a scanned document, this is the tool to reach for. Starting with iOS 18 …
Issue #1040
SwiftData is Apple’s modern persistence framework, introduced in iOS 17. It builds on top of Core Data but exposes a Swift-native API using macros and property wrappers. For most apps targeting iOS 17 or later, it replaces Core Data …
Issue #1039
Actor isolation in Swift 6 is not binary. A type can be mostly isolated while selectively exposing some members to callers from any context. A function can accept any actor and run directly on its executor without being bound to it …
Issue #1038
Swift 6 concurrency replaces Grand Central Dispatch queues, locks, and completion handlers with a structured model built around async/await, actors, and task groups. The compiler enforces isolation rules at build time, and the runtime …
Issue #1037
Enabling Swift 6 strict concurrency checking (SWIFT_STRICT_CONCURRENCY = complete) catches data races at compile time, but it does not protect you fully at runtime. The compiler also injects dynamic isolation assertions at actor and GCD …
Issue #1036
Swift 6 makes concurrency safer by enforcing actor isolation at compile time, and sometimes at runtime. One of the subtler rules is that closures automatically inherit the actor isolation of the context where they are defined, not where …
Issue #1035
Apple Intelligence is not just a brand. Since macOS 26 (Tahoe), it ships a developer-accessible framework called Foundation Models that gives your code direct access to the on-device language model powering Writing Tools and Siri. No API …
Issue #1034
Swift is a great language for building command-line tools. Package managers, code generators, deployment scripts — they’re all natural fits. But when it comes to collecting input from the user, the standard library leaves you with …
Issue #1033
Claude Code is Anthropic’s CLI for coding with AI. Getting a good setup makes a real difference — the right terminal, hooks for awareness, and the right tools to keep Claude running until the job is done.
Ghostty is a fast, …
Issue #1032
Claude Code runs fast. Sometimes too fast — you walk away, come back, and have no idea if it finished or is still working. Hooks solve this.
A hook is a shell command that runs automatically at specific points in Claude’s lifecycle. …
Issue #1031
Claude Code is good at completing tasks, but it stops when it thinks it’s done. For small, well-scoped work that’s fine. For larger projects — building out a feature, getting a test suite green, or scaffolding an entire app — …
Issue #1030
Most task systems give Claude a flat list and hope for the best. Beads is different. It tracks dependencies between tasks and only surfaces work that is actually ready — no blockers, no wasted effort.
Let’s use beads via its CLI …
Issue #1029
Claude Code ships with two built-in memory systems. CLAUDE.md lets you write persistent instructions. Auto memory lets Claude write its own notes across sessions. Understanding both — and then knowing when to add claude-mem on top — is …
Issue #1028
Running one Claude session at a time is fine for small tasks. For larger work — building a feature while fixing a bug, writing tests while refactoring — you need parallelism. Claude Code provides two tools for this: sub-agents and git …
Issue #1027
On March 31, 2026, Anthropic accidentally shipped a 59.8MB sourcemap file with a routine update to Claude Code. The file, bundled into npm package version 2.1.88, exposed nearly 2,000 files and 500,000 lines of source code to anyone who …
