Search Apple Dev Search for Swift, SwiftUI, Xcode, iOS, macOS, and Apple-platform community articles, tutorials, blogs, and write-ups.
Apple firmware and binary reverse engineering with the `ipsw` CLI: IPSW/kernelcache download/extraction, dyld_shared_cache disassembly, private headers, entitlements, Mach-O analysis, Apple internals, KEXTs, and security research.
Use when App Store listing text must be translated or market-adapted across locales, including descriptions, keywords, What's New, subtitles, names, privacy text, and App Store Connect languages. Not for non-translation metadata edits, release-note drafting, or subscription/IAP display-name localization.
Use when App Store listing metadata in canonical `./metadata` JSON needs field edits, validation, push, keyword sync, or legacy fastlane migration. Not for translation-first localization, release-note drafting, or subscription/IAP display-name localizations.
Use for the concrete macOS Developer ID notarization command path with xcodebuild export plus `asc notarization` submit, status, log, and stapling. Not for broad packaging readiness review or signing-only diagnosis.
Set territory-specific subscription and IAP pricing with `asc` setup, pricing summary, CSV import, price-point, availability, and schedule commands. Use for PPP or localized pricing strategies.

Prepare screenshots for App Store Connect. Do not hard-code Apple size tables here; asc screenshots sizes is the source of truth.
asc screenshots sizes --output table
asc screenshots sizes --all --output table
Common anchors: IPHONE_65 and IPAD_PRO_3GEN_129. Use --all for other iPhone sizes, Apple TV, Mac, Vision Pro, iMessage, or Watch.
After choosing target dimensions from ASC, inspect local screenshots with the bundled helper:
python3 "$PLUGIN_ROOT/skills/appstore-screenshot-validator/scripts/screenshot_audit.py" \
"./screenshots/iphone" --recursive --allow-size 1284x2778 --allow-rotated --fail-on-alpha
The helper reads PNG/JPEG headers only. It does not resize, rewrite, strip alpha, upload, or call ASC. Pass --json for machine-readable output.
asc screenshots sizes --all.screenshot_audit.py against candidate PNG/JPEG files; fail on alpha and hidden Unicode filename spaces before upload.sips for macOS image rewrites only after selecting an ASC target size; sips -z takes height then width.asc screenshots validate on the final directory, then asc screenshots upload --dry-run, then upload only after the dry-run is clean.Preserve originals by writing to a separate directory. Do not stretch across incompatible aspect ratios unless the user accepts the visual tradeoff. Prefer asc screenshots validate over visual inspection before upload.
