Asc Signing Setup

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.

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_13","enabled":true}]}]'
3. Create a signing certificate:
   • asc certificates list --certificate-type IOS_DISTRIBUTION
   • asc certificates create --certificate-type IOS_DISTRIBUTION --csr "./cert.csr"
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"

Rotation and cleanup

• Revoke old certificates:
  • asc certificates revoke --id "CERT_ID" --confirm
• Delete old profiles:
  • asc profiles delete --id "PROFILE_ID" --confirm

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.

# Push current ASC signing assets into an encrypted git repo
asc signing sync push \
  --bundle-id "com.example.app" \
  --profile-type IOS_APP_STORE \
  --repo "git@github.com:team/certs.git" \
  --password "$MATCH_PASSWORD"

# Pull and decrypt them into a local directory
asc signing sync pull \
  --repo "git@github.com:team/certs.git" \
  --password "$MATCH_PASSWORD" \
  --output-dir "./signing"

Notes:

• --password falls back to ASC_MATCH_PASSWORD.
• The encrypted repo follows a familiar match-style git layout for certs and profiles.
• pull writes files to disk; keychain import or profile installation is a separate step.

Notes

• Always check --help for the exact enum values (certificate types, profile types).
• Use --paginate for large accounts.
• --certificate accepts comma-separated IDs when multiple certificates are required.
• Device management uses asc devices commands (UDID required).
