**You MUST use this skill for ANY iOS UI work including SwiftUI, UIKit, layout, navigation, animations, and design.**
Provides Ktor server patterns for routing DSL, plugins (auth, CORS, serialization), Koin DI, WebSockets, services, and testApplication testing.
Conducts multi-source web research with firecrawl and exa MCPs: searches, scrapes pages, synthesizes cited reports. For deep dives, competitive analysis, tech evaluations, or due diligence.
Provides demand forecasting, safety stock optimization, replenishment planning, and promotional lift estimation for multi-location retailers managing 300-800 SKUs.
You MUST use this skill for ANY iOS UI work including SwiftUI, UIKit, layout, navigation, animations, and design.
Use this router when working with:
ios-ui vs ios-performance: When UI is slow (e.g., "SwiftUI List slow"):
Rationale: Jumping to Instruments wastes time when the fix is a known SwiftUI pattern. Profile AFTER trying domain fixes, not before.

Automated scanning agents:
| Thought | Reality |
|---|---|
| "Simple SwiftUI layout, no need for the layout skill" | SwiftUI layout has 12 gotchas. swiftui-layout covers all of them. |
| "I know how NavigationStack works" | Navigation has state restoration, deep linking, and identity traps. swiftui-nav prevents 2-hour debugging. |
| "It's just a view not updating, I'll debug it" | View update failures have 4 root causes. swiftui-debugging diagnoses in 5 min. |
| "I'll just add .animation() and fix later" | Animation issues compound. swiftui-animation-ref has the correct patterns. |
| "This UI is simple, no architecture needed" | Even small features benefit from separation. swiftui-architecture prevents refactoring debt. |
| "UX issues are just polish, we'll fix later" | Dead ends and dismiss traps cause 1-star reviews. ux-flow-audit catches them in minutes. |
| "I know how .searchable works" | Search has 6 gotchas (navigation container, isSearching level, suggestion completion). swiftui-search-ref covers all of them. |
| "I know SF Symbols, it's just Image(systemName:)" | 4 rendering modes, 12+ effects, 3 Draw playback modes, custom symbol authoring. sf-symbols has decision trees for all of them. |
| "Drag and drop is just .draggable and .dropDestination" | UTType declarations, representation ordering, file lifecycle, cross-app transfer gotchas. transferable-ref covers all of them. |
| "I'll just wrap this UIView real quick" | UIViewRepresentable has lifecycle, coordinator, sizing, and memory gotchas. uikit-bridging prevents 1-2 hour debugging sessions. |
| "tvOS is just iOS on a TV" | tvOS has no persistent storage, no WebView, a dual focus system, and two remote generations. axiom-tvos covers all the traps. |
