## What it is
A Swift library for snapshot testing that lets developers assert any value against a recorded reference image or text representation. It supports any Swift platform and format, not just UIView images, and integrates with XCTest and Swift Testing.

## Use cases
- test iOS view controllers by comparing rendered screenshots
- verify UI does not regress visually between changes
- snapshot test any Swift value as text or image
- record reference snapshots automatically on first test run
- write custom snapshot strategies for domain types

## When to choose
- you build Swift or iOS apps and want visual regression tests
- you need snapshot testing beyond UIViews, for any value or format
- you use XCTest or Swift Testing and want easy snapshot assertions

## When to avoid
- your project is not in Swift
- you need cross-platform testing outside Apple/Swift ecosystems
- you prefer behavior-based unit tests over visual comparisons

## Facets
- artifact type: library
- maturity: stable
- function: testing, e2e-testing
- domain: testing, developer-tools, mobile-development
- platform: cross-platform
- tags: snapshot-testing, screenshot-testing, xctest, swift-testing, ui-testing, swift, ios, macos
