SPM Modular Programming Architecture

SPM Modular Programming Architecture

Short summary

This article proposes an iOS architecture where the Xcode project is nearly empty and all features, shared logic, and UI live in Swift Packages. Each package is self-contained with tests, mocks, and clear dependency boundaries declared in Package.swift. An agent harness with documentation enables AI agents to contribute features while respecting architectural patterns.

  • •Thin Xcode project with all features as Swift Packages
  • •Structured concurrency separates UI and async layers cleanly
  • •Agent harness documentation helps AI contribute features correctly

Generated with AI, which can make mistakes.
