asc-xcode-build

asc-xcode-build is a skill for Claude Code, Codex from rorkai/app-store-connect-cli-skills. It costs 54 tokens per session (2,032 once invoked), scanned A, original, MIT.

A tool for building an Apple app with Xcode, creating an archive and installable package, exporting it, and uploading it to App Store Connect or TestFlight. It also manages the app’s version and build numbers.

In plain words
What is it for?
Use it to change version or build numbers, archive an app, create an IPA or PKG, export it, and upload the result.
Why use it?
It brings the steps between source code and a distributable app into one workflow. This helps avoid manual mistakes when preparing builds for testing or release.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

asc-xcode-build scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 9d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 231 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Xcode build and export

Use this skill when you need to build an app from source and prepare it for App Store Connect. Prefer asc xcode archive and asc xcode export over raw xcodebuild recipes when they fit the project.

Preconditions

  • Xcode and command line tools are installed.
  • Signing identity and provisioning profiles are available, or automatic signing is enabled.
  • App Store Connect auth is configured when upload or build lookup is needed.

Manage version and build numbers

asc xcode version view
asc xcode version edit --version "1.3.0" --build-number "42"
asc xcode version edit --next-build-number --app "APP_ID" --platform IOS
asc xcode version bump --type build
asc xcode version bump --type patch
asc xcode version bump --type build --next-build-number --app "APP_ID" --platform IOS

Use --project-dir "./MyApp" when not running from the project root. Use --project "./MyApp/App.xcodeproj" when the directory contains multiple projects. Use --target "App" and --configuration "Release" for deterministic reads and writes in multi-target or multi-configuration projects.

To avoid low build-number rejects, resolve and apply the remote-safe build number in one command:

asc xcode version edit --next-build-number --app "APP_ID" --platform IOS --output json

Version mutations validate the full change before writing and return structured output identifying the configurations and files changed. The editor follows recursive xcconfig includes and preserves unrelated project and xcconfig content. Use asc builds next-build-number separately when you only want to inspect the remote-safe value without changing the project.

Version commands read project and xcconfig settings without launching Xcode. When those settings cannot resolve the version values, the default --xcodebuild-settings-lookup auto falls back to xcodebuild -showBuildSettings and warns on stderr. Use --xcodebuild-settings-lookup never in automation that must not launch Xcode implicitly.

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
