This skill should be used when SwiftUI work requires judgment about Observation and state ownership, view identity or lifecycle, navigation, app-target concurrency, persistence, Apple-platform behavior, accessibility, performance, or architecture. Trigger on "review this SwiftUI screen", "why isn't this view updating", "should this have a ViewModel", "fix this SwiftUI navigation", "why does this list scroll badly", "fix this main-actor warning in my app target", "review my Mac app", or…
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 Inspect the project before applying a default. Read its deployment targets, Swift language mode, existing state patterns, platform targets, dependencies, and nearby code. Look up current Apple documentation before making a load-bearing claim about API behavior or availability. If a missing target, isolation setting, ownership fact, deep-link/restoration need, sync topology, offline behavior, or minimum-OS decision would materially change the answer, ask one focused question or present conditional recommendations. ## Opinions worth carrying - **Use SwiftUI's data flow directly by default.** Let views compose sources of truth with `@State`, `@Environment`, `@Bindable`, and query wrappers. Add a ViewModel when it owns real orchestration: a state machine, retries, pagination, optimistic updates, lifecycle independent of one view, or a valuable test seam. Do not introduce one merely to move properties out of a view. - **Own shared observable state at a clear ancestor.** App-wide `@Observable` instances normally originate in `App` and enter the environment. Keep ownership distinct from observation and binding extraction. …

How to install
mdr add johnkozaris/jko-claude-plugins/swiftui-expert@sha256:fada4f44628a73a9The line at the top of this page pins the label git:20260725.6c1b23d, 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.
