I triggered the update to trunk as e2e tests were failing, everything else was successful |

Everything was passing in CI besides e2et tests but the failure seemed unrelated so approving the changes 👍
Seems appropriate following up to the Ruby 3.4.9 update.

Thank you for addressing this!
I pushed another commit, tracking the result of updating Bundler (npm equivalent).
bundle update --bundler
bundle install

How AI was used in this PR
Claude Code located how CI resolves the Xcode/Ruby versions (the repo uses the
IMAGE_ID-from-.xcode-versionapproach via.buildkite/shared-pipeline-vars), confirmed no hardcoded image IDs or simulator references needed updating, and made the two version-file edits. I reviewed the changes.Proposed Changes
Bumps CI to the newly available Xcode 26.6 image and moves Ruby to the new default 3.4.9.
IMAGE_ID: $IMAGE_IDapproach, updating.xcode-versionis sufficient —.buildkite/shared-pipeline-varsderivesIMAGE_ID=xcode-26.6from it, and all pipeline files pick it up.bundle installfailure when building native-code gems such as Nokogiri, which has been present since Xcode 26.4 (https://bugs.ruby-lang.org/issues/21629). Ruby is only used here for Fastlane release tooling.Gemfile.lockhas noRUBY VERSIONpin, so no lockfile change is required. Both Buildkite and GitHub Actions (ruby/setup-rubywithbundler-cache: true) read.ruby-versionautomatically.No user-facing changes — CI/tooling only.
Testing Instructions
xcode-26.6image and succeed, including the Fastlane helper tests and PHP CLI binary build (which runsbundle install).Pre-merge Checklist
