# asc signing setup

Use this skill when you need to create or renew signing assets for iOS/macOS apps.

## Preconditions
- Auth is configured (`asc auth login` or `ASC_*` env vars).
- You know the bundle identifier and target platform.
- You have a CSR file for certificate creation, or you will let `asc certificates create --generate-csr` create one.

## Workflow
1. Create or find the bundle ID:
   - `asc bundle-ids list --paginate`
   - `asc bundle-ids create --identifier "com.example.app" --name "Example" --platform IOS`
2. Configure bundle ID capabilities:
   - `asc bundle-ids capabilities list --bundle "BUNDLE_ID"`
   - `asc bundle-ids capabilities add --bundle "BUNDLE_ID" --capability ICLOUD`
   - Add capability settings when required:
     - `--settings '[{"key":"ICLOUD_VERSION","options":[{"key":"XCODE_6","enabled":true}]}]'`
   - For the Developer Portal-only `PRIVATE_CLOUD_COMPUTE` capability, use a
     user-owned web session and the Developer Portal Bundle ID resource ID:
     - `asc web bundle-ids capabilities enable --bundle-id "BUNDLE_RESOURCE_ID" --capability PRIVATE_CLOUD_COMPUTE --confirm`
     - This capability is not available through the public App Store Connect
     capability enum. If the cached session cannot access Developer Portal,
       clear its scoped cache, then log in again with the same binary:
       - `asc web auth logout --apple-id "[email protected]"`
       - `asc web auth login --apple-id "[email protected]"`
   - For App Groups, the public API can enable `APP_GROUPS` but cannot create or
     associate App Group resources. Use an Account Holder or Admin web session:
     - `asc web app-groups list --paginate --output table`
     - `asc web app-groups create --name "Example Shared" --identifier "group.com.example.app.shared" --confirm`
     - `asc web app-groups assign --group "GROUP_RESOURCE_ID" --bundle-id "BUNDLE_RESOURCE_ID" --confirm`
     - Resolve the opaque group ID with `asc web app-groups list` and the opaque
       Bundle ID resource ID with `asc bundle-ids list`. A changed assignment
       invalidates provisioning profiles containing that App ID, so regenerate
       affected profiles before the next signed build.
3. Create a signing certificate:
   - `asc certificates list --certificate-type IOS_DISTRIBUTION`
   - `asc certificates create --certificate-type IOS_DISTRIBUTION --csr "./cert.csr"`
   - Or generate a key and CSR inline:
     - `asc certificates create --certificate-type IOS_DISTRIBUTION --generate-csr --key-out "./signing/dist.key" --csr-out "./signing/dist.csr"`
   - For Wallet passes, create the Pass Type ID first, then create its certificate:
     - `asc pass-type-ids create --identifier "pass.com.example" --name "Example Pass"`
     - `asc certificates create --certificate-type PASS_TYPE_ID --pass-type-id "PASS_TYPE_ID" --csr "./pass.csr"`
     - `asc pass-type-ids certificates list --pass-type-id "PASS_TYPE_ID" --paginate`
4. Create a provisioning profile:
   - `asc profiles create --name "AppStore Profile" --profile-type IOS_APP_STORE --bundle "BUNDLE_ID" --certificate "CERT_ID"`
   - Include devices for development/ad-hoc:
     - `asc profiles create --name "Dev Profile" --profile-type IOS_APP_DEVELOPMENT --bundle "BUNDLE_ID" --certificate "CERT_ID" --device "DEVICE_ID"`
5. Download the profile:
   - `asc profiles download --id "PROFILE_ID" --output "./profiles/AppStore.mobileprovision"`
6. Inspect and install the downloaded profile locally when needed:
   - `asc profiles inspect --path "./profiles/AppStore.mobileprovision" --output table`
   - `asc profiles inspect --path "./profiles/AppStore.mobileprovision" --entitlements --output markdown`
   - `asc profiles local install --path "./profiles/AppStore.mobileprovision"`
   - `asc profiles local list --output table`
   - On macOS, the default directory follows the active Xcode: Xcode 16 or newer uses `~/Library/Developer/Xcode/UserData/Provisioning Profiles`; Xcode 15 or older uses `~/Library/MobileDevice/Provisioning Profiles`. Hosts without a full active Xcode fall back to the legacy directory and print a note to stderr.
   - Pass `--install-dir` when automation must target a fixed directory.

## Rotation and cleanup
- Revoke old certificates:
  - `asc certificates revoke --id "CERT_ID" --confirm`
- Audit remote provisioning profiles before deleting or rotating:
  - `asc profiles list --profile-state ACTIVE,INVALID --paginate --output json`
  - Apple `profileState` is not a complete expiration signal: some profiles can have a past `expirationDate` while still reporting `ACTIVE`. For true expired-profile audits, compare `expirationDate` against the current date instead of relying only on `INVALID`.
- Delete old profiles:
  - `asc profiles delete --id "PROFILE_ID" --confirm`
- Clean local Xcode provisioning profiles:
  - `asc profiles local clean --expired --dry-run`
  - `asc profiles local clean --expired --confirm`
  - Check the resolved directory in the dry-run output before confirming, or pin it with `--install-dir`.

## Shared team storage with `asc signing sync`
Use this when you want a lightweight, non-interactive alternative to fastlane match for encrypted git-backed certificate/profile storage.

```bash
# Protect secret inputs before use
chmod 600 "./signing-sync-password" "./distribution.p12" "./distribution-p12-password"

# Push a usable private identity with its matching certificate and profile
asc signing sync push \
  --bundle-id "com.example.app" \
  --profile-type IOS_APP_ADHOC \
  --repo "[email protected]:team/certs.git" \
  --password-file "./signing-sync-password" \
  --identity "./distribution.p12" \
  --identity-password-file "./distribution-p12-password" \
  --output json
