Additional information

This is likely caused by #75322 which introduced the failing lines.

@asl Can you take a look?

On my plate. What is the best way to test the changes locally?

[xymus]

You can look at the log in CI for the precise build-script invocation. I think the extra flags you'd need here are simply --ios --test.

Ok, thanks, will try to figure out. --ios never worked for me with errors like ninja: error: unknown target 'swift-test-stdlib-iphonesimulator-arm64'

[xymus]

You may need to fully delete the build folder for that issue, apparently --reconfigure is not enough for that one. I would also expect a @swift-ci please test macOS to run these tests for iOS if you want to leave it up to the CI.

No, swift-ci does not run these tests. The full CI run was green on the PR, I switched to smoke tests for the final merge because main was broken on Linux. buildbot preset also does not run this configuration
