Superhighway is a networking library heavily inspired by tiny-networking, but designed primarily for use with Combine. It defines an Endpoint type which encapsulates the relationship between a URLRequest and the Decodable entity it represents.

A Simple Example

struct Repository: Decodable {
    let id: Int64
    let name: String

func repository(author: String, name: String) -> Endpoint<Repository> {
    return Endpoint(json: .get, url: URL(string: "https://api.github.com/repos/\(author)/\(name)")!)

let endpoint = repository(author: "rhysforyou", name: "Superhighway")

This simply gives us the description of an endpoint, to actually load it, we need to subscribe to its publisher:

subscriber = URLSesion.shared.endpointPublisher(endpoint)
    .sink(receiveCompletion: { print("Completed: \($0)") },
          receiveValue: { print("Value: \($0)") })

If the subscriber is cancelled or deallocated before it finishes, any networking operations will be halted.


The recommended way to use Superhighway is through the Swift Package manager. For Xcode projects, simply add this repository to the project's Swift packages list. For projects using a Package.swift file, add the following:

// swift-tools-version:4.0
import PackageDescription

let package = Package(
    // ...
    dependencies: [
        .package(url: "https://github.com/rhysforyou/Superhighway.git", "0.4.0"..<"0.5.0")
    targets: [
            name: "MyTarget",
            dependencies: ["Superhighway"])

Other package managers such as CocoaPods and Carthage are officially unsupported, but this entire library is encapsulated in a single Endpoint.swift file which can be copied into an existing project and used as-is.
