# DebugSnapshots: Public beta

**[Point-Free Pointers](https://daily.dev/sources/pointfree)** · 6 min read · 1 upvotes · 0 comments

## Summary

DebugSnapshots, a Swift library from Point-Free, has entered public beta. It provides debugging and exhaustive testing tools for reference types, particularly @Observable classes in SwiftUI apps. The @DebugSnapshot macro generates a snapshot value representing model state, enabling diff-based logging of state changes on every method call via OSLog (debug builds only). For testing, the expect() function allows exhaustive assertions on state transitions — if any unaccounted state changes occur, the test fails with a focused diff. The library supports fine-grained control via @LogChanges, @DebugSnapshotTracked, @DebugSnapshotIgnored, and @DebugSnapshotConvertible macros, and handles nested models and enums. It uses the CustomDump library under the hood for focused diffs on large collections.
