What layers are defined in this iOS architecture?

The architecture defines six layers: Domain (models), Services (SDK wrappers), Repository (data), State (observable management), UseCases (business logic), and Presentation (UI).

Does this skill support Firebase or external API integration?

Yes, it includes specific guidelines for integrating external SPM packages for Firebase Authentication and HTTP API clients within the Repository and State layers.

Can I use this skill with standard SwiftUI projects?

Yes, it is specifically designed for modern SwiftUI development, utilizing the @Observable macro and modular SPM package configurations.

How does it prevent circular dependencies?

It provides a strict dependency map and a checklist that prohibits lower layers (like Domain) from importing higher layers (like Presentation or State).

Standardizes iOS application architecture using Swift Package Manager to ensure strict layer separation and maintainable codebases.

This skill provides a comprehensive framework for building iOS applications based on Clean Architecture principles and Swift Package Manager (SPM). It defines a structured six-layer system—Domain, Services, Repository, State, UseCases, and Presentation—to enforce strict dependency rules and improve long-term project maintainability. By guiding the implementation of @Observable state management and integrating specialized external modules for authentication and routing, it helps developers avoid common pitfalls like circular dependencies and UI logic leakage into the business layer.
