SF Pro: Variable Axes, Optical Sizing, And The Dynamic Type Contract
Apple's system font ships with three variable axes and continuous optical sizing. The vocabulary that makes typography work across the Apple platforms.
AI & TechnologyWriting
Thoughts on design, development, AI infrastructure, and building products.
The Privacy Manifest Deep Dive: What Counts As Data Collection
Apple's privacy manifest is a structured contract, not a checkbox: four sections, five required-reason API categories, SDK rules, common gotchas.
AI & TechnologyHooks 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 & TechnologyWhat 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 & TechnologySingle Source Of Truth: SwiftData, MCP, iCloud
Three callers can write to the same shopping list: a human, Apple Intelligence, and an external agent. Truth has to live somewhere. Pick the substrate.
AI & TechnologyThree Surfaces: Human, Apple Intelligence, Agent
Every iOS app capability faces three surfaces: human, Apple Intelligence, agent. Each has different obligations, rendering, latency, and trust posture.
AI & TechnologyFoundation Models Agentic Workflow: In-App Vs Tooling LLM
Two LLMs touch a Swift app. The on-device model that ships with the app and the agent that wrote the code. Different stacks, different obligations.
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 & 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 & 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 & 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.
