Review, write, and fix SwiftUI gesture interactions. Apply modern gesture APIs with correct composition, state management, and conflict resolution using Swift 6.3 patterns.

Layout and component patterns for SwiftUI apps targeting iOS 26+ with Swift 6.3. Covers stack and grid layouts, list patterns, scroll views, forms, controls, search, and overlays. Patterns are backward-compatible to iOS 17 unless noted.

Navigation patterns for SwiftUI apps targeting iOS 26+ with Swift 6.3. Covers push navigation, multi-column layouts, sheet presentation, tab architecture, and deep linking. Patterns are backward-compatible to iOS 17 unless noted.

Refactor SwiftUI views toward small, explicit, stable types with MV-first defaults. \n \n Enforces view ordering (environment, state, computed vars, init, body, helpers) and strongly prefers dedicated subview types over computed some View helpers for non-trivial sections \n Defaults to Model-View architecture: local state in views, shared dependencies in environment, business logic in services/models, view models only when explicitly required or already present \n Extracts actions and side effec

Diagnose and fix SwiftUI rendering bottlenecks through code review, Instruments profiling, and targeted remediation. \n \n Covers view invalidation storms, unstable list identity, expensive body computations, layout thrash, and image decoding issues with concrete code examples and fixes \n Includes step-by-step Instruments profiling workflow using the SwiftUI template to identify high body-evaluation counts and CPU hotspots \n Explains identity and lifetime mechanics, lazy loading patterns, and

Discipline-enforcing skill for building layouts that respond to available space rather than device assumptions. Covers tool selection, size class limitations, iOS 26 free-form windows, and common anti-patterns.

Best practices and patterns for building SwiftUI views, navigation, and state management. \n \n Covers state ownership strategies (from @State and @Binding to @Observable on iOS 17+), async/await patterns with .task , and environment injection for shared dependencies \n Includes cross-cutting references for NavigationStack routing, sheet presentation, deep linking, and app-level wiring with concrete ownership rules \n Provides component-specific guidance via indexed references, with anti-pattern

Systematically scan Apple's developer documentation via the Sosumi MCP, identify deprecated SwiftUI APIs and their modern replacements, and update swiftui-expert-skill/references/latest-apis.md.
