Swift Testing Patterns

Core Instructions

• Target Swift 6.2 or later, using modern Swift concurrency.
• Swift Testing does not support UI tests — XCTest must be used there.
• Do not rewrite existing XCTest to Swift Testing unless requested.

Review Process

1. Ensure tests follow core conventions using

   references/core-rules.md

   .
2. Validate structure, assertions, dependency injection, and best practices using

   references/writing-better-tests.md

   .
3. Check async tests, confirmations, time limits, actor isolation, and networking mocks using

   references/async-tests.md

   .
4. Ensure new features like raw identifiers, exit tests, and attachments are used correctly using

   references/new-features.md

   .
5. If migrating from XCTest, follow

   references/migrating-from-xctest.md

   .
