This skill provides standardized patterns for decoupling Swift applications from external side effects like the file system, network, and hardware APIs through protocol-based dependency injection. It guides developers in creating focused protocols, default production implementations, and deterministic mock objects compatible with the modern Swift Testing framework. By emphasizing Swift concurrency safety (Sendable and actors) and lean protocol design, it ensures code remains modular, maintainable, and verifiable across different environments such as unit tests, integration tests, and SwiftUI previews.
