Swift Testing: The Framework Replacing XCTest, and What Stays In XCTest
Swift Testing ships with Xcode 16+ and Swift 6. Macros, traits, parametrized tests, parallel by default. Migrate incrementally; UI tests stay in XCTest.
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 & TechnologyCore ML On-Device Inference: The Patterns That Actually Ship
Core ML runs models on Neural Engine, GPU, or CPU. The patterns that ship: model conversion, dispatch hinting, latency budgets, and quantization.
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 & TechnologytvOS Focus Engine: SwiftUI Patterns for the Siri Remote
Apple TV navigates by focus, not touch. SwiftUI's .focusable, @FocusState, focusSection, and prefersDefaultFocus are the vocabulary. The patterns that ship.
AI & TechnologyApple Vision Framework: On-Device CV Most Devs Skip
Apple Vision ships more than two dozen on-device CV operations. Most devs default to OpenAI Vision for tasks Vision performs in milliseconds, free, on-device.
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 & TechnologyThe Apple Platform Matrix: Which Targets Deserve Which App
iOS, iPad, Mac, Watch, Vision, TV. Six platforms, six obligations. Picking Apple targets is a product decision before it is an engineering one.
AI & TechnologySwiftData 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.
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 & 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 & 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.
