The Swift codeql package is an experimental and unsupported work in progress.

First ensure you have Bazel installed, e.g. with

brew install bazelisk

then run

bazel run //swift:create-extractor-pack

which will install swift/extractor-pack.

Using --search-path=swift/extractor-pack will then pick up the Swift extractor. You can also use --search-path=., as the extractor pack is mentioned in the root codeql-workspace.yml.

Notice you can run bazel run :create-extractor-pack if you already are in the swift directory.

Run

bazel run //swift/codegen

to update generated files. This can be shortened to bazel run codegen if you are in the swift directory.
