Choose the tool that matches your workflow.

Use ascdir when a compact App Store declaration, field-level plans, and explicit guards are the priority. Use fastlane when you need build, signing, testing, and deployment in one ecosystem. They can also work together: fastlane can build and upload the binary, then ascdir can manage metadata, TestFlight distribution, submission, and release.
