Or you can build and install libuv manually. But you modify module.modulemap in this case.

1. Clone libuv
2. cd libuv
3. sh autogen.sh
4. ./configure --prefix=/usr
5. make install (with sudo as needed)
6. modify module.modulemap :

       module Libuv [system] {
           header "/usr/include/uv.h"
           link "uv"
           export *
       }

Usage

Add dependency to your Package.swift file :

import PackageDescription

let package = Package(
    dependencies: [
        .Package(url: "https://github.com/Trevi-Swift/swift-libuv.git", majorVersion: 1)
    ]
)

Then you can import the module and use libuv functions :

import Libuv

let loop = uv_default_loop()
uv_run(loop, UV_RUN_DEFAULT)
print("Event loop: \(loop)")

Warning : You may set the environment variable when executing after building.
