## What it is
A Swift library that wraps Apple's MultipeerConnectivity framework with a Codable-based API, letting iOS, macOS, and tvOS devices exchange typed messages over Wi-Fi, peer-to-peer Wi-Fi, and Bluetooth. It provides a simple MultipeerTransceiver class for broadcasting and receiving any Codable payload between nearby peers.

## Use cases
- send messages between nearby iOS devices without a server
- build a peer-to-peer multiplayer game on Apple platforms
- exchange Codable data between a Mac and an iPhone over local network
- sync app state across devices via Bluetooth or peer-to-peer Wi-Fi
- broadcast structured payloads to nearby peers in Swift
- discover and communicate with devices on the local network

## When to choose
- you need serverless device-to-device communication on iOS, macOS, or tvOS
- you want a simple Codable-based API instead of raw MultipeerConnectivity
- your app exchanges small structured messages between nearby devices

## When to avoid
- you need internet-based or remote communication rather than nearby peers
- you target platforms outside Apple's ecosystem
- you need large file transfers or streaming rather than small Codable messages
