Swift Protocol-Based DI & Testing
Implements protocol-based dependency injection and mocking patterns to create highly testable Swift applications.
This skill provides a robust framework for architecting testable Swift code by abstracting external dependencies like file systems, network calls, and APIs behind focused protocols. It streamlines the creation of mock implementations and integrates seamlessly with the modern Swift Testing framework and Swift Concurrency (Sendable/Actors). By utilizing these patterns, developers can write deterministic tests that cover complex error paths and edge cases without performing actual I/O operations, ensuring code reliability across app environments, tests, and SwiftUI previews.
