Code Generators Production ready code generators for iOS and macOS apps. Unlike advisory skills (review, audit), these skills generate working code tailored to your project. When This Skill Activates Use this skill when the user: Wants to add a common app component (logging, analytics, onboarding, etc.) Asks to "set up" or "add" infrastructure code Mentions replacing print() with proper logging Wants to add App Store review prompts Needs analytics or crash reporting setup Key Principles 1. Context Aware Generation Before generating code, skills will: Read existing project structure and patterns Detect deployment targets and Swift version Identify architecture patterns (MVVM, TCA, etc.) Check for existing implementations to avoid conflicts 2. Protocol Based Architecture Provider dependent code uses protocols for easy swapping: 3. Platform Detection Skills detect iOS vs macOS and App Store vs direct distribution to generate appropriate code. Available Generators Read relevant module files based on the user's needs: logging setup/ Replace print() statements with structured os.log/Logger. Audit existing print() usage Generate AppLogger infrastructure Migrate print → Logger with proper privacy levels analytics setup/ Protocol based analytics with swappable providers. TelemetryDeck, Firebase, Mixpanel support NoOp implementation for testing/privacy Easy provider switching onboarding generator/ Value moment first onboarding — races a new user to the first felt experience of the app's promised outcome. Branches on ready now vs. later, one decision per screen Root swap presentation, phase first gating, resume safe hand offs into existing features Local notification implementation intentions for the "later" branch Value moment reach rate instrumentation (local only, no analytics SDK required) Classic paged/stepped welcome carousel kept as an explicit fallback for explain first apps review prompt/ Smart App Store review prompts.
