What I Refuse To Write About
A blog cluster's voice comes from what it refuses to publish, not what it ships. Categorical, pattern, and interesting refusals each shape what the cluster is.
AI & TechnologyWriting
Thoughts on design, development, AI infrastructure, and building products.
Hooks For Apple Development: Patterns That Save The Project
An iOS agent has the developer's signing keys, builds, and project file reachable. Hooks bound the blast radius. Four shipping patterns.
AI & TechnologyApp Intents vs MCP: The Routing Question
Two protocols, one app. App Intents expose your app to Apple Intelligence. MCP exposes the same domain to Claude, ChatGPT, and the rest. The routing question.
AI & TechnologyFoundation Models On-Device LLM: The Tool Protocol
iOS 26's Foundation Models framework puts a 3B-parameter LLM on every Apple Intelligence device. The Tool protocol is the surface that makes the model useful.
AI & TechnologywatchOS Runtime Is a Contract, Not a Background Task
watchOS has no iOS-style background. WKExtendedRuntimeSession is the contract; without it, the app suspends on wrist drop. Pattern shipped in Return.
AI & TechnologySwiftData's Real Cost Is Schema Discipline
SwiftData's API is two macros. The cost is what happens after you ship. Optional fields are the cheap migration; non-optional adds need a VersionedSchema.
AI & TechnologyLive Activities Are a State Machine, Not a Badge
Return's Live Activity looks like a Lock Screen countdown. It is a five-state lifecycle machine with three dismissal paths. The production code and bugs.
AI & TechnologyRealityKit And The Spatial Mental Model
RealityKit is an entity-component-system, not SwiftUI in 3D. Anchors place entities in real space. Five ways the model differs from a window.
AI & TechnologyWhat SwiftUI Is Made Of
SwiftUI is a result-builder DSL on top of a value-typed View tree. Once the substrate is visible, AnyView, Group, and ViewBuilder stop being mysterious.
AI & TechnologyFive Apple Platforms, Three Shared Files: How Return Actually Ships Cross-Platform SwiftUI
Return runs on iPhone, iPad, Mac, Apple Watch, and Apple TV. Three Swift files are shared across all five targets out of 40 total. The rest is duplicated, and that is on purpose.
AI & TechnologyClaude Code Mac Desktop + Remote Control: A CLI User's Guide
What changes when you move from `claude` in a terminal to the Mac desktop app, and how /remote-control lets you steer a local session from your phone without losing Xcode, MCP, or files.
AI EngineeringLiquid Glass in SwiftUI: Three Patterns From Shipping Return on iOS 26
Apple's Liquid Glass is a one-line SwiftUI API. Three patterns from Return go beyond .glassEffect(): glass on text via Core Text glyph paths, mirror reflection, and HUD overlays.
