Single 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 & TechnologyWriting
Thoughts on design, development, AI infrastructure, and building products.
Foundation 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 & 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 & 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 & 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 & 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 & 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 & 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 & TechnologyHealthKit + SwiftUI on iOS 26: Authorization, Sample Types, and Cross-Platform Patterns
Real production patterns from Water (water tracking, HKQuantitySample) and Return (mindful sessions, HKCategorySample). Permission UX, async wrappers, watchOS variants, and the trap to avoid.
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.
