Markdown instructions

A SKILL.md file the model loads on demand, so it only costs tokens when a request actually matches.

Works with any LLM

AI skills are plain Markdown, not provider-specific code, so this works with GPT, Claude, Gemini, Grok, or a local model.

Self-contained

Everything the model needs lives in the instructions — no extra files to sync.

Open source

Published by rorkai on GitHub. Read the source before you install it.

Installation

Install the Asc Xcode Build AI skill in TypingMind to use it with any LLM, or drop it into another agent that reads SKILL.md.

Install in TypingMind

TypingMind installs a skill straight from its GitHub folder — it reads SKILL.md, bundles the resource files, and stores the result locally.

Open the app and go to Plugins → Skills.
Choose "Install from GitHub".
Paste the skill folder URL below and confirm.
https://github.com/rorkai/app-store-connect-cli-skills/tree/main/skills/asc-xcode-build
Enable the skill in any chat where you want it available.

Plugins → Skills → Add skill → From GitHub URL, then paste the folder URL and press Continue.

Install in another agent

Any agent that reads the Agent Skills format can use this skill — copy the folder into that agent's skills directory.

Claude Code — .claude/skills

git clone --depth 1 https://github.com/rorkai/app-store-connect-cli-skills.git /tmp/app-store-connect-cli-skills
mkdir -p .claude/skills
cp -r /tmp/app-store-connect-cli-skills/skills/asc-xcode-build .claude/skills/asc-xcode-build

Restart Claude Code after copying so it picks up the new skill.

Use it in TypingMind

Enable Asc Xcode Build in any TypingMind chat and the model takes it from there. Its name and description sit in the system prompt, and the moment a request matches, the model loads the full instructions itself — you never invoke it by hand, and it costs no tokens until it is actually used.

The model loads Asc Xcode Build on its own as soon as a request matches it.

Works with any AI model

AI skills are plain Markdown instructions rather than provider-specific code, so Asc Xcode Build is not tied to the model it was written for. Install it once in TypingMind and use it with GPT-5, Claude, Gemini, Grok, DeepSeek, Mistral, Llama, or a local model you run yourself — all on your own API keys.

Loaded only when it is needed

The system prompt carries just the name and description. The instructions are fetched on the first matching request, so an idle skill costs nothing.

Switch models mid-chat

Because the skill is instructions rather than code, changing model does not break it — the next model reads the same SKILL.md.

Skill instructions

This is the SKILL.md content the model loads. Read it before installing — a skill is instructions your model will follow.

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

bash
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:

bash
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.

Compile without archiving

Use asc xcode build for an ordinary simulator, device, or CI validation build. Provide exactly one project or workspace and a scheme.

bash
asc xcode build \
  --project "App.xcodeproj" \
  --scheme "App" \
  --destination "platform=iOS Simulator,name=iPhone 17 Pro Max,OS=27.0" \
  --no-code-signing \
  --result-bundle-path ".asc/artifacts/App.xcresult" \
  --output json

When --derived-data-path is omitted, asc uses a stable cache outside the source checkout. The result-bundle destination must not already exist. Xcode logs go to stderr and the structured result goes to stdout.

Preferred iOS/tvOS/visionOS build flow

1. Archive with asc

bash
asc xcode archive \
  --workspace "App.xcworkspace" \
  --scheme "App" \
  --configuration Release \
  --clean \
  --archive-path ".asc/artifacts/App.xcarchive" \
  --xcodebuild-flag=-destination \
  --xcodebuild-flag=generic/platform=iOS \
  --output json

Use --project "App.xcodeproj" instead of --workspace for project-only apps.

2. Export with asc

By default, asc xcode export generates App Store Connect export options with automatic signing. It uses a local export destination unless --wait is set, in which case it uses direct upload:

bash
asc xcode export \
  --archive-path ".asc/artifacts/App.xcarchive" \
  --ipa-path ".asc/artifacts/App.ipa" \
  --xcodebuild-flag=-allowProvisioningUpdates \
  --output json

Generate a plist separately when it needs review, reuse, or manual signing:

bash
asc xcode export-options generate \
  --archive-path ".asc/artifacts/App.xcarchive" \
  --output-path ".asc/ExportOptions.plist" \
  --output json

For manual signing, add --signing-style manual and optionally --team-id "TEAM_ID". Existing files require --overwrite.

For an IPA installable on registered devices, use Xcode's current release-testing method. The older ad-hoc spelling is deprecated by Xcode and is not accepted by asc:

bash
asc xcode export \
  --archive-path ".asc/artifacts/App.xcarchive" \
  --ipa-path ".asc/artifacts/App.ipa" \
  --method release-testing \
  --signing-style manual \
  --team-id "TEAM_ID" \
  --output json

Generate the release-testing plist separately when it needs review or reuse:

bash
asc xcode export-options generate \
  --archive-path ".asc/artifacts/App.xcarchive" \
  --method release-testing \
  --signing-style manual \
  --team-id "TEAM_ID" \
  --output-path ".asc/ExportOptions.release-testing.plist" \
  --output json

release-testing always exports locally and cannot be combined with --wait. An explicit --export-options plist cannot be combined with --method, --signing-style, or --team-id. For device/profile reconciliation, isolated signing, private publication, resumability, and live verification, use the asc-ad-hoc-distribution skill instead of assembling those stages manually.

To upload directly through Xcode and wait for App Store Connect processing, omit --export-options and add --wait:

bash
asc xcode export \
  --archive-path ".asc/artifacts/App.xcarchive" \
  --ipa-path ".asc/artifacts/App.ipa" \
  --wait \
  --output json

3. Upload or publish

Upload an exported IPA:

bash
asc builds upload --app "APP_ID" --ipa ".asc/artifacts/App.ipa" --wait

Distribute to TestFlight:

bash
asc publish testflight --app "APP_ID" --ipa ".asc/artifacts/App.ipa" --group "GROUP_ID" --wait

Publish to the App Store:

bash
asc publish appstore --app "APP_ID" --ipa ".asc/artifacts/App.ipa" --version "1.2.3" --wait
asc publish appstore --app "APP_ID" --ipa ".asc/artifacts/App.ipa" --version "1.2.3" --wait --submit --confirm

macOS App Store flow

Archive with the helper:

bash
asc xcode archive \
  --project "MacApp.xcodeproj" \
  --scheme "MacApp" \
  --configuration Release \
  --clean \
  --archive-path ".asc/artifacts/MacApp.xcarchive" \
  --xcodebuild-flag=-destination \
  --xcodebuild-flag=generic/platform=macOS \
  --output json

If your macOS export produces a .pkg, export it with the helper, then upload the package:

bash
asc xcode export \
  --archive-path ".asc/artifacts/MacApp.xcarchive" \
  --pkg-path ".asc/artifacts/MacApp.pkg" \
  --xcodebuild-flag=-allowProvisioningUpdates \
  --output json

asc builds upload \
  --app "APP_ID" \
  --pkg ".asc/artifacts/MacApp.pkg" \
  --version "1.0.0" \
  --build-number "123" \
  --wait

For .pkg uploads, --version and --build-number are required because they are not auto-extracted like IPA metadata. Add --export-options "ExportOptions.plist" when the project needs a custom export configuration.

Raw xcodebuild fallback

Use raw xcodebuild only when neither asc xcode archive --help nor asc xcode export --help covers a project-specific option. Prefer passing extra arguments through --xcodebuild-flag first.

bash
xcodebuild -showBuildSettings -scheme "App"

Troubleshooting

No profiles for bundle ID during export

Add --xcodebuild-flag=-allowProvisioningUpdates to asc xcode export.
Verify the Apple ID is logged into Xcode.
Verify profiles with the asc-signing-setup skill.

CFBundleVersion too low

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

Then rebuild and upload again.

Build rejected for missing macOS icon

macOS requires ICNS icons with all required sizes. Fix the asset catalog, rebuild, then export/upload again.

Notes

Prefer asc xcode archive and asc xcode export for deterministic local artifacts.
The default generated export method remains app-store-connect; request --method release-testing explicitly for registered-device installs.
Use --overwrite only when replacing existing local artifacts intentionally.
Use --wait on upload/publish paths when the next step depends on processed builds.
For submission readiness, use asc-submission-health.

Frequently asked questions

What does the Asc Xcode Build AI skill do?

Build, archive, generate export options, export, upload, and manage Xcode version/build numbers with the current asc xcode helpers. Use when creating an IPA or PKG for App Store Connect, TestFlight, or registered-device release testing.

Why use Asc Xcode Build on TypingMind?

Because you install it once and use it with any model. Asc Xcode Build is plain Markdown rather than provider-specific code, so the same skill runs on GPT-5, Claude, Gemini, Grok, or a local model — and you can switch model mid-chat without it breaking. TypingMind runs on your own API keys, so you pay providers directly instead of a per-seat subscription, and your skills and chats stay in your own storage.

How do I install Asc Xcode Build in TypingMind?

Open Plugins → Skills → Install from GitHub in TypingMind and paste https://github.com/rorkai/app-store-connect-cli-skills/tree/main/skills/asc-xcode-build. TypingMind reads its SKILL.md and installs it as a skill you can enable per chat.

Which AI models can use Asc Xcode Build?

Any model you connect in TypingMind. AI skills are plain Markdown instructions rather than provider-specific code, so GPT, Claude, Gemini, Grok, and local models can all load this skill when a request matches it.

How many AI models can I use with Asc Xcode Build?

As many as you like. As long as a model supports skills, you can use Asc Xcode Build with it — GPT, Claude, Gemini, Grok, DeepSeek, Mistral, Llama and more — all on TypingMind with your own API keys.

Is the Asc Xcode Build AI skill free?

Yes. It is published on GitHub by rorkai under the MIT license. You only pay your own AI provider for the tokens you use.

What are AI skills?

An AI skill is a reusable instruction bundle that teaches an AI model how to do one specific task. It follows the open Agent Skills format: a SKILL.md file with a name and description, plus any scripts, templates or reference files the model may need. The model reads the instructions only when your request matches the skill, so an installed skill costs nothing until it is used.

How are AI skills different from plugins or MCP servers?

A plugin or MCP server gives a model new tools to call — code that runs somewhere and returns a result. An AI skill gives the model knowledge and process instead: how to approach a task, which steps to follow, what good output looks like. Skills are plain Markdown, so they need no server, no API key and no runtime, and they work with any model.
