Design, implement, validate, and troubleshoot App Intents, App Entities, App Shortcuts, and system-surface integrations. Use when exposing a focused app action or content to Siri, Spotlight, Shortcuts, widgets, controls, Live Activities, or hardware interactions.
Guide AppKit app-structure decisions for macOS apps across app delegates, status-item menu bar apps, responder-chain menus, windows, controllers, restoration, archiving, Observation, and mixed AppKit/SwiftUI composition. Use when the user wants help deciding where AppKit responsibilities belong or how to avoid steering a macOS app into SwiftUI-only structure when AppKit owns the behavior.
Plan and safely automate officially supported Apple Developer provisioning and CloudKit workflows through the App Store Connect REST API, Xcode-aware local discovery, cktool, and CKTool JS. Use when inspecting or changing bundle IDs, capabilities, certificates, devices, provisioning profiles, CloudKit schemas, or sandbox test data while keeping portal-only configuration, credentials, dry runs, and confirmation gates explicit.
Guide Apple image decoding, encoding, metadata, thumbnails, multi-frame sources, and representation bridging across Image I/O, Core Graphics, AppKit NSImage and NSImageRep, UIKit UIImage, Core Image, and Core Video. Use when image work involves files, data, representations, orientation, scale, color, metadata, or conversion rather than pixel effects or visual recognition.
Guide Apple platform typography decisions and implementation across SwiftUI Font, UIKit UIFont, AppKit NSFont, San Francisco system fonts, SF Pro, SF Compact, SF Mono, SF Pro Rounded, New York serif design, Dynamic Type, text styles, fontDesign, fontWeight, fontWidth, monospaced digits, custom font bundle integration, font licensing and redistribution boundaries, accessibility scaling, and Xcode font asset validation. Use when a task mentions Apple typography, San Francisco, SF Pro, SF Compact, SF Mono, New York, Dynamic Type, UIFontMetrics, preferredFont, NSFont.TextStyle, custom fonts, UIAppFonts, ATSApplicationFontsPath, or text style repair.
Guide Apple UI accessibility implementation and review for SwiftUI-first code, with UIKit and AppKit bridge guidance plus explicit verification expectations and testing handoffs. Use when the user wants help making Apple UI accessible, reviewing accessibility semantics, shaping the accessibility tree, or planning Apple-platform accessibility verification without collapsing the work into generic design review or Xcode test execution.
Guide ARKit TrueDepth face tracking, face anchors, geometry, topology, transforms, eye transforms, blend shapes, face-driven animation, world-plus-face tracking, body anchors, skeletons, joint transforms, scale estimation, privacy, and diagnostics. Use when ARKit face geometry or 3D body tracking is primary rather than Face ID authentication or Vision frame analysis.
Guide ARKit world tracking, anchors, planes, ray casting, feature points, scene depth, smoothed depth, LiDAR scene reconstruction, meshes, classification, environment texturing, world maps, relocalization, reference images and objects, geographic anchors, visionOS providers, privacy, and diagnostics. Use when Apple-platform spatial sensing or environment understanding is primary.
