getreadystack/swift6-concurrency-lint repository overview

⁠Swift 6 Concurrency Migration Lint

11 rules that name the .swift lines Swift 6 language mode rejects — 13 findings, 6 build-blocking, on the 47-line fixture

⁠Run

docker run --rm -v "$PWD":/work getreadystack/swift6-concurrency-lint /work/file

The same 11 rules as the VS Code extension, in a container. Mount a folder on /work.

⁠Free

• Lints the .swift files you open and names every Swift 6 language-mode blocker with its line number and its replacement shape
• --rules lists every rule

⁠With a licence ($29 once)

• Exports one Swift 6 migration report for the whole repository — every file ranked by blocking errors, committable and CI-readable

docker run --rm -e READYSTACK_LICENSE=<key> -v "$PWD":/work getreadystack/swift6-concurrency-lint --dir /work --ci

One hour of a contract iOS engineer, at the $100/hour rates common in the US market, costs more than this licence does once.

⁠Use from an AI agent (MCP)

Claude Code · Cursor · Windsurf · any MCP client - add to your MCP config:

{ "mcpServers": { "swift6-concurrency-lint": { "command": "npx", "args": ["-y", "@readystack/swift6-concurrency-lint", "--mcp"] } } }

Tools: check_text and check_file (free) · check_dir (licence). The agent gets every finding with the line number.

⁠Use in CI

- name: Swift 6 Concurrency Migration Lint
  run: npx -y @readystack/swift6-concurrency-lint --dir . --ci

(container: docker run --rm -v "$PWD:/work" getreadystack/swift6-concurrency-lint --dir /work --ci)

The folder sweep, reports and CI mode need one licence — one payment, no subscription. Set READYSTACK_LICENSE=<key> or run --license <key> once.
