## What it is
ZIP Foundation is a Swift library for creating, reading, and modifying ZIP archive files. It is built on Apple's libcompression for high performance, supports in-memory archives, large files, and runs on Apple platforms and Linux with no third-party dependencies.

## Use cases
- zip files and directories in swift
- unzip an archive in an ios app
- read individual entries from a zip file
- create zip archives in memory
- add or remove entries from an existing zip
- track progress and cancel long zip operations

## When to choose
- you need ZIP support in Swift on Apple platforms or Linux
- you want a dependency-free, high-performance compression library
- you need in-memory archive handling or progress tracking

## When to avoid
- you need formats other than ZIP such as tar or 7z
- you work outside Swift or outside the supported platforms

## Facets
- artifact type: library
- maturity: stable
- function: compression, file-system
- domain: files, developer-tools, cross-platform
- platform: -
- tags: zip, archive, swift-package-manager, libcompression, macos, ios, linux, swift
