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 & TechnologyThe 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 & 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 & 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 & 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 & 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 & TechnologyvisionOS 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 & 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 & 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.
