visionOS Spatial Patterns Beyond the Window
Apps that float an iPad UI on Vision Pro miss the platform. Windows, Volumes, Immersive Spaces, ornaments, attachments: the visionOS-native vocabulary.
AI & TechnologyWriting
Thoughts on design, development, AI infrastructure, and building products.
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 Tools API: How Apps Plug Into Apple Intelligence's Writing Layer
iOS 18 introduced Writing Tools. iOS 26 makes adoption a single property for standard text views, and a designed coordinator API for custom text engines.
AI & TechnologySymbol Effects: SwiftUI's Built-In Animation Vocabulary For Every Icon
SF Symbols ships an animation vocabulary every iOS app can speak. Bounce, pulse, scale, replace, variable color, breathe: already designed, accessible, free.
AI & TechnologyAccessibility As Platform: Personal Voice, Live Speech, Eye Tracking, Music Haptics
Personal Voice, Live Speech, Eye Tracking, Music Haptics, Vocal Shortcuts: accessibility as platform features, not app responsibilities.
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 & 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 & 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 & 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 & 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 & 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 & 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.
