This is a CodeQL extractor based on tree-sitter.

To build the extractor, run scripts/create-extractor-pack.sh

The vendored tree-sitter-swift grammar lives at extractor/tree-sitter-swift/. After editing grammar.js (or any other grammar source), run scripts/regenerate-grammar.sh to:

• regenerate extractor/tree-sitter-swift/src/{parser.c, grammar.json, node-types.json} (and the src/tree_sitter/*.h headers) via tree-sitter generate; and
• refresh extractor/tree-sitter-swift/node-types.yml, the human-readable companion to src/node-types.json produced by yeast's node_types_yaml binary.

node-types.yml is the recommended review surface for grammar changes — it shows the impact of a grammar tweak on the named node kinds, fields, and child types in a form much easier to read than the raw JSON.

• If you changed the extractor code, always rebuild it before running tests.

• To run all tests, run codeql test run --search-path extractor-pack ql/test

• Do not edit .expected files manually. To update the expected output, pass --learn to the codeql test run command.

• To run a specific test, pass the specific directory to the codeql test run command instead of ql/test.
