Swift analysis fails with Xcode 26.0 (works fine with Xcode 16)

[maoyama]

When I specify Xcode 26.0 to build in my project, the following error occurs. ( In Xcode 16, it worked well with the same build script.

https://github.com/maoyama/Tempo/actions/runs/17705247368/job/50316169931

Encountered a fatal error while running "/Users/runner/hostedtoolcache/CodeQL/2.23.0/arm64/codeql/codeql database finalize --finalize-dataset --threads=3 --ram=6144 /Users/runner/work/_temp/codeql_databases/swift". Exit code was 32 and last log line was: CodeQL detected code written in Swift but this run didn't build any of it, or CodeQL could not process any of it. Ensure that you have provided manual build steps (see https://docs.github.com/en/code-security/code-scanning/creating-an-advanced-setup-for-code-scanning/codeql-code-scanning-for-compiled-languages#about-specifying-build-steps-manually) for Swift between the 'init' and 'analyze' Actions, and check the workflow run logs (see https://docs.github.com/en/actions/monitoring-and-troubleshooting-workflows/using-workflow-run-logs). For more information, review our troubleshooting guide at https://gh.io/troubleshooting-code-scanning/no-source-code-seen-during-build . See the logs for more details.

Hi @maoyama,

As far as Swift is concerned, we do not support beta versions or release candidates of Xcode. After Apple has released the final version, we will likely add support within a few weeks.

@jketema Thank you for your reply! I'll wait for the latest version of Xcode to be supported.

Do we have an update on when that will be now that Xcode 26 / macOS 26 / Swift 6.2 are no longer in beta?

It's being worked on here at the moment.

This will be fixed in CodeQL 2.23.4 which will be released in a few weeks.

when CodeQL 2.23.4 will be released?

[jketema]

when CodeQL 2.23.4 will be released?

In the next few weeks, as I wrote above.

Thanks @jketema. I was expecting any estimated date you may provide.That would be really helpful :)

CodeQL 2.23.5 has been released. Note that we skipped 2.23.4. Also note that at the time of writing 2.23.5 has not yet been rolled out to all the action runners.
