2. Edit local files

Canonical files are written under:

• metadata/app-info/<locale>.json for app-level fields: name, subtitle, privacyPolicyUrl, privacyChoicesUrl, privacyPolicyText

• metadata/version/<version>/<locale>.json for version fields: description, keywords, marketingUrl, promotionalText, supportUrl, whatsNew

Copyright is not a localization field. Manage it with:

asc versions update --version-id "VERSION_ID" --copyright "2026 Your Company"

3. Validate before upload

asc metadata validate --dir "./metadata" --output table

For subscription apps, include the extra Terms of Use / EULA heuristic:

asc metadata validate --dir "./metadata" --subscription-app --output table

4. Preview and apply

Run a dry run first:

asc metadata push --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata" --dry-run --output table

Apply after the plan looks correct:

asc metadata push --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata"

Use asc metadata apply when the user wants the apply-named command shape for the same canonical files:

asc metadata apply --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata" --dry-run

asc metadata apply --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata"

Keyword-only workflow

Use this when only the version-localization keywords field should change:

asc metadata keywords diff --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata"

asc metadata keywords apply --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata" --confirm

For importing keyword research:

asc metadata keywords import --dir "./metadata" --version "1.2.3" --locale "en-US" --input "./keywords.csv"

asc metadata keywords sync --app "APP_ID" --version "1.2.3" --platform IOS --dir "./metadata" --input "./keywords.csv"

Quick field updates

For one-off version-localization edits, pass an explicit version selector. Use --version-id for deterministic updates when you already have it, or --version plus --platform when working from a version string.

asc apps info edit --app "APP_ID" --version-id "VERSION_ID" --locale "en-US" --whats-new "Bug fixes and improvements"

asc apps info edit --app "APP_ID" --version "1.2.3" --platform IOS --locale "en-US" --description "Your app description here"

asc apps info edit --app "APP_ID" --version "1.2.3" --platform IOS --locale "en-US" --keywords "keyword1,keyword2,keyword3"

asc apps info edit --app "APP_ID" --version "1.2.3" --platform IOS --locale "en-US" --support-url "https://support.example.com"

For app-info fields, prefer the post-create setup command:

asc app-setup info set --app "APP_ID" --primary-locale "en-US" --privacy-policy-url "https://example.com/privacy"

asc app-setup info set --app "APP_ID" --locale "en-US" --name "Your App Name" --subtitle "Your subtitle"

Lower-level localization files

Use .strings files when the user specifically wants import/export files instead of canonical JSON:

asc localizations list --version "VERSION_ID" --output table

asc localizations download --version "VERSION_ID" --path "./localizations"

asc localizations upload --version "VERSION_ID" --path "./localizations" --dry-run

asc localizations upload --version "VERSION_ID" --path "./localizations"

For app-info localizations:

asc apps info list --app "APP_ID" --output table

asc localizations list --app "APP_ID" --type app-info --app-info "APP_INFO_ID" --output table

asc localizations download --app "APP_ID" --type app-info --app-info "APP_INFO_ID" --path "./app-info-localizations"

asc localizations upload --app "APP_ID" --type app-info --app-info "APP_INFO_ID" --path "./app-info-localizations" --dry-run

asc localizations upload --app "APP_ID" --type app-info --app-info "APP_INFO_ID" --path "./app-info-localizations"

Legacy fastlane metadata

Use this only for existing fastlane-format trees:

asc migrate export --app "APP_ID" --version-id "VERSION_ID" --output-dir "./fastlane"

asc migrate validate --fastlane-dir "./fastlane"

asc migrate import --app "APP_ID" --version-id "VERSION_ID" --fastlane-dir "./fastlane" --dry-run

asc migrate import --app "APP_ID" --version-id "VERSION_ID" --fastlane-dir "./fastlane"

Agent behavior

• Start with asc metadata pull unless the user specifically asks for .strings or fastlane metadata.

• Always run asc metadata validate before remote writes.

• Preview remote changes with --dry-run when the command supports it.

• For quick edits, always pass --version-id or --version plus --platform; do not rely on ambiguous latest-version behavior.

• Keep app-info fields and version fields separate.

• Use --output table for human verification and JSON for automation.
