Diagnose and fix SwiftUI performance issues through code review and Instruments profiling guidance. \n \n Classifies symptoms (slow rendering, janky scrolling, CPU spikes, memory growth, hangs, excessive view updates) and performs code-first review against common anti-patterns like invalidation storms, unstable list identity, and layout thrash. \n Guides users through Instruments profiling when code review alone is inconclusive, with structured intake checklists and trace analysis. \n Provides r

This skill encodes design principles derived from comparing polished, production-quality SwiftUI apps against poorly-built ones. The patterns here represent what separates an app that feels "right" from one where the margins, spacing, and text sizes just look "off."

SwiftUI search is environment-based and navigation-consumed. You attach .searchable() to a view, but a navigation container (NavigationStack, NavigationSplitView, or TabView) renders the actual search field. This indirection is the source of most search bugs.

Embed and manage web content in SwiftUI using the native WebKit-for-SwiftUI APIs introduced for iOS 26, iPadOS 26, macOS 26, and visionOS 26. Use this skill when the app needs an integrated web surface, app-owned HTML content, JavaScript-backed page interaction, or custom navigation policy control.
