## What it is
AsyncHTTPClient is an HTTP client library for Swift built on top of SwiftNIO. It provides asynchronous, non-blocking request APIs with first-class Swift Concurrency support, streaming bodies, TLS, and automatic HTTP/2.

## Use cases
- make http requests from a swift app
- async await http client for swift
- download response bodies as a stream
- call rest apis from a swift server
- http client with tls and http2 support
- follow redirects in swift

## When to choose
- you are building Swift applications or server-side Swift services that need HTTP requests
- you want non-blocking, high-performance networking on SwiftNIO
- you need Swift Concurrency async/await or EventLoopFuture APIs
- you need streaming downloads, TLS, or HTTP/2 over HTTPS

## When to avoid
- you need a full-featured HTTP client with cookie storage or caching out of the box
- your project is not in Swift
- you need a browser or high-level REST client abstraction rather than a low-level HTTP client
