Code Signing

Certificate management, provisioning profiles, entitlements configuration, CI/CD signing setup, and distribution build preparation for iOS/macOS apps.

When to Use This Skill

Use when you need to:

• ☑ Set up code signing for a new project or CI/CD pipeline
• ☑ Debug any code signing error (certificate, profile, entitlement, Keychain)
• ☑ Configure signing for App Store, TestFlight, or Ad Hoc distribution
• ☑ Manage certificates and profiles across a team
• ☑ Set up fastlane match for team-wide certificate management
• ☑ Understand automatic vs manual signing tradeoffs
• ☑ Add a new capability that requires entitlement changes
• ☑ Fix CI/CD signing failures (errSecInternalComponent, locked keychain)
