## What it is
swiftenv is a Swift version manager inspired by pyenv that lets you install and switch between multiple Swift toolchains. It supports global, per-project, and environment-variable-based Swift version selection.

## Use cases
- install multiple swift versions
- switch swift version per project
- set a global swift version
- manage swift toolchains on linux
- pin swift version for ci builds
- override swift version via environment variable

## When to choose
- you work on multiple swift projects needing different toolchains
- you develop swift on linux or macos and want pyenv-like workflows
- you need reproducible swift versions in CI like Travis or Heroku

## When to avoid
- you only ever use one Swift version bundled with Xcode
- you need dependency management rather than toolchain management (use Swift Package Manager)
- you need managed Swift versions on Windows or other unsupported platforms

## Facets
- artifact type: cli-tool
- maturity: stable
- function: cli, developer-tools, version-control
- domain: developer-tools, programming-languages
- platform: cli
- tags: swift, version-manager, pyenv-inspired, shell, command-line, macos, linux
