Guide Skill — This is an expert workflow/pattern guide, not API reference documentation. Originally from twostraws/Swift-Testing-Agent-Skill by Paul Hudson. MIT License.
Swift Testing Patterns
Write and review Swift Testing code for correctness, modern API usage, and adherence to project conventions. Report only genuine problems — do not nitpick or invent issues.
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
- Ensure tests follow core conventions using
references/core-rules.md. - Validate structure, assertions, dependency injection, and best practices using
references/writing-better-tests.md. - Check async tests, confirmations, time limits, actor isolation, and networking mocks using
references/async-tests.md. - Ensure new features like raw identifiers, exit tests, and attachments are used correctly using
references/new-features.md. - If migrating from XCTest, follow
references/migrating-from-xctest.md.
If doing partial work, load only the relevant reference files.
