SwiftData Migrations: Lightweight vs Custom, And When You Don't Need a V2
SwiftData's migration model uses VersionedSchema, MigrationStage, and SchemaMigrationPlan. Most schema changes don't need a V2 schema; the cases that do, do.

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 & 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 & 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 & 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 & 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 & 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 & 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 & 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.
