Protocol-based dependency injection for testable Swift code
by affaan-mFree
Description
swift-protocol-di-testing is an agent skill from the ECC collection by affaan-m, listed on skills.sh. It sets out protocol-based dependency injection for testable Swift code. External dependencies such as the file system, the network and iCloud are hidden behind small, focused protocols, so tests can swap in mocks and run deterministically with no real input or output. The skill uses Swift Testing for the tests and shows how to exercise error-handling paths without making real failures happen. It applies when Swift code touches the file system, the network or external APIs, when error paths need testing, when a module has to work in the app, in tests and in SwiftUI previews, and when the architecture has to be testable under Swift concurrency with actors and Sendable. Its core pattern is to define a separate, narrow protocol for each external concern. A skill is a SKILL.md file of instructions that an AI agent loads when a task calls for it. It is free and open source, and the skills.sh listing shows all three security audits passing.…
