Thanks a lot for putting this together and for iterating on the CI setup.

I’m closing this PR because the CI work has been superseded by the newer maintenance/CI updates on master.

The current CI now covers the main validation paths we need for PRs and pushes:

• SwiftPM tests
• Korean locale SwiftPM tests
• release build
• upstream test/API parity checks
• version consistency check
• geocoding metadata updater smoke test
• CocoaPods lint
• Xcode scheme tests

This PR also contains a large experimental reusable-action/coverage setup and now conflicts with the updated workflow structure. Rather than merging it as-is, we should keep the current CI as the baseline.

The coverage-reporting and simulator-selection ideas are still useful. If we want to revisit them, they would be very welcome as smaller PRs based on the latest master.

Thanks again for the contribution and for helping move the project’s CI forward.

@iziz - No worries...I was just iterating on it to try to get it working (and also experiment on using AI to help code up all the github action logic).

I saw that you went ahead and did your own thing, so yeah...I will hopefully get a chance to revise this work, and start building off of what you did to add additional features in the future).
