> swift-tooling

Configure SPM packages, SwiftLint, and build settings for Swift projects. Use when managing Swift packages with SPM, configuring build settings, or enforcing Swift code quality. (triggers: Package.swift, .swiftlint.yml, package, target, dependency)

> axiom-swiftui-debugging-diag

Use when SwiftUI view debugging requires systematic investigation - view updates not working after basic troubleshooting, intermittent UI issues, complex state dependencies, or when Self._printChanges() shows unexpected update patterns - systematic diagnostic workflows with Instruments integration

> axiom-swiftui-nav

Use when implementing navigation patterns, choosing between NavigationStack and NavigationSplitView, handling deep links, adopting coordinator patterns, or requesting code review of navigation implementation - prevents navigation state corruption, deep link failures, and state restoration bugs for iOS 18+

> axiom-swiftui-containers-ref

Reference — SwiftUI stacks, grids, outlines, and scroll enhancements through iOS 26

> axiom-swiftui-26-ref

Use when implementing iOS 26 SwiftUI features - covers Liquid Glass design system, performance improvements, @Animatable macro, 3D spatial layout, scene bridging, WebView/WebPage, AttributedString rich text editing, drag and drop enhancements, and visionOS integration for iOS 26+

> axiom-realitykit

Use when building 3D content, AR experiences, or spatial computing with RealityKit. Covers ECS architecture, SwiftUI integration, RealityView, AR anchors, materials, physics, interaction, multiplayer, performance.

> axiom-scenekit

Use when working with SceneKit 3D scenes, migrating SceneKit to RealityKit, or maintaining legacy SceneKit code. Covers scene graph, materials, physics, animation, SwiftUI bridge, migration decision tree.

> axiom-textkit-ref

TextKit 2 complete reference (architecture, migration, Writing Tools, SwiftUI TextEditor) through iOS 26

> axiom-ios-ui

Use when building, fixing, or improving ANY iOS UI including SwiftUI, UIKit, layout, navigation, animations, design guidelines. Covers view updates, layout bugs, navigation issues, performance, architecture, Apple design compliance.

> axiom-mapkit

> axiom-mapkit-ref

MapKit API reference — SwiftUI Map, MKMapView, Marker, Annotation, MKLocalSearch, MKDirections, Look Around, MKMapSnapshotter, clustering, overlays, GeoToolbox PlaceDescriptor, geocoding

> axiom-ux-flow-audit

Use when auditing user journeys, checking for UX dead ends, dismiss traps, buried CTAs, missing empty/loading/error states, or broken data paths in iOS apps (SwiftUI and UIKit).

> ios-hig-design

Design native iOS interfaces following Apple Human Interface Guidelines. Use when the user mentions "iPhone app", "iPad layout", "SwiftUI", "UIKit", "Dynamic Island", "safe areas", or "HIG compliance". Covers navigation patterns, accessibility, SF Symbols, and platform conventions. For general UI polish, see refactoring-ui. For affordance design, see design-everyday-things.

> axiom-swiftui-nav-diag

Use when debugging navigation not responding, unexpected pops, deep links showing wrong screen, state lost on tab switch or background, crashes in navigationDestination, or any SwiftUI navigation failure - systematic diagnostics with production crisis defense

> axiom-swiftui-layout

Use when layouts need to adapt to different screen sizes, iPad multitasking, or iOS 26 free-form windows — decision trees for ViewThatFits vs AnyLayout vs onGeometryChange, size class limitations, and anti-patterns preventing device-based layout mistakes

> axiom-uikit-bridging

Use when wrapping UIKit views/controllers in SwiftUI, embedding SwiftUI in UIKit, or debugging UIKit-SwiftUI interop issues. Covers UIViewRepresentable, UIViewControllerRepresentable, UIHostingController, UIHostingConfiguration, coordinators, lifecycle, state binding, memory management.

> axiom-swiftui-gestures

> axiom-swiftui-layout-ref

Reference — Complete SwiftUI adaptive layout API guide covering ViewThatFits, AnyLayout, Layout protocol, onGeometryChange, GeometryReader, size classes, and iOS 26 window APIs

> axiom-swiftui-debugging

Use when debugging SwiftUI view updates, preview crashes, or layout issues - diagnostic decision trees to identify root causes quickly and avoid misdiagnosis under pressure

> swiftui-pro

Comprehensively reviews SwiftUI code for best practices on modern APIs, maintainability, and performance. Use when reading, writing, or reviewing SwiftUI projects.
