Drop-in SwiftUI sticky header component with progressive blur effect matching Apple Music, Photos, and App Store styles.
AttributedString patterns for rich text formatting, alignment, selection, and SwiftUI integration. Use when working with styled text, text editing, or AttributedString APIs.
Start here for any iOS or SwiftUI task. Coordinates best-practice guides, correctness checks, and full Apple API references. Use before navigating to other Apple skills — for building, reviewing, refactoring, or debugging iOS apps.
Mobile app instrumentation and Capture SDK setup for bitdrift in iOS, Android, and React Native apps, including new installs and extending existing integrations with screen tracking, network monitoring, logs, fields, and spans.
Design and build native-feeling mobile app screens and flows (SwiftUI, UIKit, React Native, Expo, Flutter, mobile web prototypes) that match top App Store apps. Use for onboarding, tab and stack navigation, lists, forms, settings, paywalls, players, sheets and empty or error states. Researches whole journeys in real apps via Seenry MCP (the flow from the app it is based on, the look from the app it should look like), then enforces navigation doors, a mechanical slop pre-flight and a beat-the-reference gate.
Use when building ANY tvOS app - covers Focus Engine, Siri Remote input, storage constraints (no Document directory), no WebView, TVUIKit, TextField workarounds, AVPlayer tuning, Menu button state machines, and tvOS-specific gotchas that catch iOS developers
Build a proper macOS settings/preferences window with liquid glass support for macOS 26 (Tahoe). Use this skill whenever the user asks to create a settings window, preferences UI, settings view, or preferences pane for a macOS app. Also trigger when the user mentions "liquid glass settings", "NavigationSplitView settings", "grouped Form settings", "macOS settings layout", or wants to add/fix/rebuild a settings screen in any native macOS SwiftUI app. This includes phrases like "add settings to my app", "create a preferences window", "my settings look wrong", "fix my settings UI", or even just "I need a settings view". If the user is building a macOS app and mentions settings or preferences in any context, use this skill.
Design and build two-pane experiences for iPhone Duo — the real pixel and point dimensions of each display and each half, the exact hinge callback types (onHingeChange / UIHingeInteraction), hinge-driven effects, pose-to-pattern mapping (companion pane, dual view, list-detail, tabletop controls), two-pane paywalls and fold-aware onboarding. Use when sizing a layout or asset for iPhone Duo, wiring a hinge callback, choosing what goes in each pane, or designing onboarding and purchase flows that span the fold.
Use the iPhone Duo hinge angle for interactions and effects, support Split View multitasking and multiple app scenes, and pair UI across both displays with scene accessories including CameraCaptureAccessory. Use when building fold-driven effects, multi-window support, or dual-display experiences.

OS development from scratch skill for bootloader through context switching. Use when building a minimal x86-64 OS, setting up GDT/IDT/page tables, writing keyboard/serial drivers, or using QEMU for kernel boot. Activates on queries about bootloader, long mode, page tables, IDT, PIC/APIC, xv6, or x86_64-elf-gcc.
