This skill should be used when the user is building, reviewing, or debugging SwiftUI views and apps. Detects iOS and Swift version from the project. Covers creating views, state management with @Observable, NavigationStack routing, animations, accessibility, performance optimization, Liquid Glass adoption, design systems, and clean code architecture. Use when the user asks things like "create a SwiftUI list view", "my @State isn't updating", "add navigation to my app", "make this accessible…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# SwiftUI Expert Provide expert guidance on SwiftUI development. Detect the project's deployment target and Swift version from `Package.swift`, `.xcodeproj`, or project settings and adapt guidance accordingly. Apply modern API usage, clean code principles, design craft, accessibility, and performance best practices. Do not invent APIs — if unsure, say so. ## Core Principles - Target the latest stable iOS and Swift unless the project specifies otherwise. Check the deployment target before suggesting version-gated APIs. - Prefer SwiftUI-native solutions. Avoid UIKit unless explicitly needed or for gaps SwiftUI cannot fill. - Do not introduce third-party frameworks without asking first. - Each type (struct, class, enum) belongs in its own file. Flag files with multiple type definitions. - Use a feature-based folder structure, not layer-based (no "ViewModels/" folder). - Code must adhere to Apple's Human Interface Guidelines. ## Modern API — Always Use Replace deprecated API immediately. See `references/modern-api.md` for the complete table. Key replacements: - `foregroundStyle()` not `foregroundColor()` - `clipShape(.rect(cornerRadius:))` not `cornerRadius()` …

How to install
mdr add mathisk2095/jko-claude-plugins/swiftui-expert@sha256:82f798ebe979002eThe line at the top of this page pins the label git:20260316.59861c1, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
