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
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:
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.
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
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:
Generate a plist separately when it needs review, reuse, or manual signing:
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:
Generate the release-testing plist separately when it needs review or reuse:
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:
3. Upload or publish
Upload an exported IPA:
Distribute to TestFlight:
Publish to the App Store:
macOS App Store flow
Archive with the helper:
If your macOS export produces a .pkg, export it with the helper, then upload the package:
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.
Troubleshooting
No profiles for bundle ID during export
- Add
--xcodebuild-flag=-allowProvisioningUpdatestoasc xcode export. - Verify the Apple ID is logged into Xcode.
- Verify profiles with the
asc-signing-setupskill.
CFBundleVersion too low
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 archiveandasc xcode exportfor deterministic local artifacts. - The default generated export method remains
app-store-connect; request--method release-testingexplicitly for registered-device installs. - Use
--overwriteonly when replacing existing local artifacts intentionally. - Use
--waiton upload/publish paths when the next step depends on processed builds. - For submission readiness, use
asc-submission-health.
