swift-swiftui SKILL.md skillA
swift-swiftui from tomcounsell/ai is an agent skill: a SKILL.md folder an AI agent loads when a task calls for it.
mdr add tomcounsell/ai/swift-swiftui@git:20261027.b1054fcPins git:20261027.b1054fc in mdr.lock. Pin the fingerprint instead.

Swift 6 and SwiftUI code rules for macOS apps, including concurrency, state, SwiftData, AppKit bridges, and fixes for common compiler errors. Use when writing, reviewing, or debugging Swift code in a Mac app, or on concurrency, Sendable, or "not in scope" errors.
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
# Swift and SwiftUI
The code is right when it compiles with zero warnings in Swift 6 language
mode and the app does what the story says. For how it should look, call the
Skill tool with `mac-design`. For copyable view code, read
[../../design/mac-design/patterns.md](../../design/mac-design/patterns.md).
## Concurrency
The template sets main-actor default isolation: every type and function runs
on the main actor unless you say otherwise. UI code needs no annotations.
| Work | Put it in |
| --- | --- |
| UI state, views, view models | Default (main actor) |
| CPU-heavy pure work (parsing, image work, diffing) | A `nonisolated` function marked `@concurrent` |
| Shared mutable state used off the main thread | An `actor` |
| A C callback (event tap, Carbon hotkey, CoreAudio listener) | A `nonisolated` static func that hops back with `Task { @MainActor in ... }` |
- Data that crosses actors is `Sendable`: structs and enums of `Sendable`
values, or `final class` with only `let` properties.
- `MainActor.assumeIsolated { }` inside a callback you know runs on the main
thread (a main run loop `Timer`, a main queue notification).

How to install
mdr add tomcounsell/ai/swift-swiftui@sha256:4e77525d38691e40The line at the top of this page pins the label git:20261027.b1054fc, 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.
