Thoughts on design, development, AI infrastructure, and building products.
watchOS workout sessions move through a six-state lifecycle. iOS 26 brought HKWorkoutSession to iPhone. The state machine, the live builder, and the delegate.
AI & TechnologyCore ML runs models on Neural Engine, GPU, or CPU. The patterns that ship: model conversion, dispatch hinting, latency budgets, and quantization.
AI & TechnologyApple's privacy manifest is a structured contract, not a checkbox: four sections, five required-reason API categories, SDK rules, common gotchas.
AI & TechnologyPersonal Voice, Live Speech, Eye Tracking, Music Haptics, Vocal Shortcuts: accessibility as platform features, not app responsibilities.
AI & TechnologyApple TV navigates by focus, not touch. SwiftUI's .focusable, @FocusState, focusSection, and prefersDefaultFocus are the vocabulary. The patterns that ship.
AI & TechnologyApple 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 & TechnologyApple's system font ships with three variable axes and continuous optical sizing. The vocabulary that makes typography work across the Apple platforms.
AI & TechnologySwiftData's migration model uses VersionedSchema, MigrationStage, and SchemaMigrationPlan. Most schema changes don't need a V2 schema; the cases that do, do.
AI & TechnologySF Symbols ships an animation vocabulary every iOS app can speak. Bounce, pulse, scale, replace, variable color, breathe: already designed, accessible, free.
AI & TechnologyApps that float an iPad UI on Vision Pro miss the platform. Windows, Volumes, Immersive Spaces, ornaments, attachments: the visionOS-native vocabulary.
AI & TechnologyiOS 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 & TechnologyiOS 26 introduces SpeechAnalyzer with SpeechTranscriber + SpeechDetector modules, an on-device replacement for SFSpeechRecognizer. When to migrate.
