Asc Metadata Sync
This handles the full lifecycle of App Store Connect metadata: pull canonical JSON files for app-info and version localizations, edit them locally, validate against character limits and required fields, then push changes back with a dry-run preview. It replaces the old fastlane metadata workflow with a cleaner pull/push cycle, though it still supports .strings files and legacy migrations when you need them. The validate step catches issues before you hit the API, and the keyword-only commands are handy for ASO work. If you're tired of clicking through App Store Connect forms for every localization update, or you want metadata in git alongside your code, this is the workflow.

asc metadata sync
Use this skill to keep App Store metadata in sync with App Store Connect. Prefer the canonical asc metadata workflow for app-info and version localization fields. Use the lower-level asc localizations and asc migrate commands only when the user specifically needs .strings files or legacy fastlane-format metadata.
Current canonical workflow
1. Pull canonical metadata
asc metadata pull --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata"
If the app has multiple app-info records, resolve the app-info ID first and pass it explicitly:
asc apps info list --app "APP_ID" --output table
asc metadata pull --app "APP_ID" --app-info "APP_INFO_ID" --version "1.2.3" --platform IOS --dir "./metadata"
2. Edit local files
Canonical files are written under:
metadata/app-info/<locale>.jsonfor app-level fields:name,subtitle,privacyPolicyUrl,privacyChoicesUrl,privacyPolicyTextmetadata/version/<version>/<locale>.jsonfor version fields:description,keywords,marketingUrl,promotionalText,supportUrl,whatsNew
Copyright is not a localization field. Manage it with:
