A lightweight Swift HTTP library

Basic Usage

Building a request

First step is to build a request. You make requests by providing extension on top of Request type:

extension Request {
  static let func login(_ body: UserBody) -> Self where Output == UserResponse {
    .post("login", body: body)

And... voila! We defined a login(_:) request which will request login endpoint by sending a UserBody and waiting for a UserResponse. Now it's time to use it.

You can also use an enum to define your Request path:

enum MyAppEndpoint: String, Path {
  case login

extension Request {
  static let func login(_ body: UserBody) -> Self where Output == UserResponse {
    .post(MyAppEndpoint.login, body: body)

Sending a request

To send a request use a Session instance. Session is somewhat similar to URLSession but providing additional functionalities.

let session = Session(baseURL: URL(string: "https://github.com")!, encoder: JSONEncoder(), decoder: JSONDecoder())

session.publisher(for: .login(UserBody(username: "pjechris", password: "MyPassword")))

You can now use the returned publisher however you want. Its result is similar to what you have received with URLSession.shared.dataTaskPublisher(for: ...).decode(type: UserResponse.self, decoder: JSONDecoder()).

A few words about Session:

  • baseURL will be prepended to all call endpoints
  • You can skip encoder and decoder if you use JSON
  • You can provide a custom URLSession instance if ever needed


Protocol Interceptor enable powerful request interceptions. This include authentication, logging, request retrying, etc...


RequestInterceptor allow to adapt a or retry a request whenever it failed:

  • adaptRequest method is called before making a request and allow you to transform it adding headers, changing path, ...
  • rescueRequestError is called whenever the request fail. You'll have a chance to retry the request. This can be used to re-authenticate the user for instance


ResponseInterceptor is dedicated to intercept and server responses:

  • adaptResponse change the server output
  • receivedResponse notify about the server final response (a valid output or error)
