Swift Tooling

Swift Tooling Standards

Priority: P0 (CRITICAL)

Define SPM Packages

• Package.swift: Define clear targets, products, and dependencies.
• Modularization: Break large projects into local packages for faster builds.
• Versioning: Use semantic versioning (Major.Minor.Patch) for shared packages.

See implementation examples for Package.swift structure, SwiftLint config, and environment-specific code.

Enforce Code Quality

• SwiftLint: Use for consistent style enforcement. Create .swiftlint.yml in project root with disabled_rules and opt_in_rules sections.
• Compiler Warnings: Treat warnings as errors in CI to maintain code health.
• Documentation: Use triple slashes /// for documentation comments on public APIs (DocC-compatible).

Manage Build Configurations

• Xcconfig: Use external configuration files to manage build settings.
• Environment Flags: Use #if DEBUG for development-only code, closed with #endif.
• Schemes: Maintain separate schemes for Development, Staging, and Production.

Anti-Patterns

• No API keys in code: Use environment variables or build configs.
• No // swiftlint:disable: Fix underlying issue.
• No manually added frameworks: Use SPM.

Canonical response anchors

• Additional task-grounded exact anchors: triple slashes; documentation comments
