How do you pick Swift base OS image and what is the status of the multiple images?

A few questions on the status of Swift and how to correctly use it:

• Looking at https://github.com/google/oss-fuzz/tree/master/infra/base-images/base-builder-swift, it seems there are three *Docker files, but https://google.github.io/oss-fuzz/getting-started/new-project-guide/swift-lang/ doesn't actually mention how to pick between them. It's also not clear the differences. What are the differences, and how should one configure a project to pick a specific one?

• Looking at https://github.com/google/oss-fuzz/tree/master/infra/base-images/base-builder, there are three different install_swift*.sh scripts, but looking back at the base-builder-swift/ directory; two of the *Docker files refer to the install_swift.sh, so one of the scripts appears not to be used? Is that also by design?

• But looking at the install scripts closer, install_swift_ubuntu_24_04.sh seems to different in that it might be trying to support both versions, which cycles me back to should there just be one version of the script with the conditional code or should they all exist with minor edits in each?
