Swift Testing Pro writes and reviews Swift Testing code for correctness, modern API usage, and project conventions - and reports only genuine problems, without nitpicking. It targets Swift 6.2+ with modern concurrency, covers async tests, confirmations, time limits, actor isolation, networking mocks, and raw identifiers, and provides migration guidance from XCTest.

CorpusIQ Use Cases¶

Use Case	How
Swift client work	Test review and migration for Swift codebases
Test quality standard	The no-nitpick doctrine matches our verification standards
Modern API guidance	Swift 6.2 concurrency and async testing patterns

Integration with CorpusIQ¶

CorpusIQ is the connector layer that lets AI assistants read the systems a business already runs on - accounting, payments, CRM, email, files and analytics - and answer with the source named. It is read-only by design: it retrieves data and never writes to, or acts in, a connected system, which is what makes it safe to point at live accounts.

This page is part of the CorpusIQ directory, the reference we maintain for the MCP server and agent-skill ecosystem. Run alongside CorpusIQ, a third-party server like this one can be combined with a company's own business data in a single answer.

Limitations / Verification¶

Swift Testing does not support UI tests - XCTest must be used there
Single-skill cluster; all three security audits pass (verified on skill page)
