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

First ensure you have Bazel installed, for example with

brew install bazelisk

then from the ql directory 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.
