swift6-concurrency skillA

swift6-concurrency is agent-read markdown (skill) from wei18/apple-dev-skills: Default to Swift 6 language mode with complete concurrency checking from the first line of code; treat all in-house types as needing Sendable; isolate third-party deps that lag with @preconcurrency. Invoke when writing Package.swift, picking the Swift language mode in Xcode build settings, or when asked "should I turn on strict concurrency?"..

Indexed from public GitHub and served as immutable, content-addressed versions. Install it pinned to an exact SHA-256 with the mdr CLI, and every file is verified against the hash recorded here before it reaches your agent. The deterministic audit below grades the latest version, and the same file always earns the same grade.

How to install

Latest version
mdr add wei18/apple-dev-skills/swift6-concurrency@git:20260907.6297feb
Exact content
mdr add wei18/apple-dev-skills/swift6-concurrency@sha256:76bbd00827a10c23

Pin to a label to follow the author's releases, or to a sha256 to freeze the exact bytes forever. Either way the resolved hash is written to mdr.lock, and mdr install reproduces it on any machine.
