Open Source Swift HTTP Clients

Pitaya is a Swift HTTP / HTTPS networking library for people. Inspired by Alamofire and JustHTTP. Carthage is a decentralized dependency manager that automates the process of adding frameworks to your Cocoa application.

Swift OpenAPI Generator is a Swift Package plugin that reads an OpenAPI document (YAML/JSON) and emits strongly typed client and server code. It removes boilerplate around request/response wiring so you focus on business logic while keeping strict type safety. The generated code uses a separate runtime package with pluggable transports and middlewares, enabling you to swap HTTP stacks or add cross-cutting concerns without touching the API layer. Swift-idiomatic naming and code structure in outputs. The project tracks ergonomic details like Swift casing conventions for generated types and properties. Releases provide a predictable upgrade path as the generator/runtimes evolve. Together, the plugin and runtime form a standardized pipeline from OpenAPI to production-ready Swift code.

Just is a client-side HTTP library inspired by python-requests, HTTP for Humans. URL queries, custom headers, form, JSON HTTP body. Redirect control. Multipart file upload along with form values. Basic/digest authentication, cookies, timeouts. Synchronous/asynchronous requests. Upload/download progress tracking for asynchronous requests. Link headers and friendly accessible results.

Netfox provides a quick look on all executed network requests performed by your iOS or OSX app. It grabs all requests - of course yours, requests from 3rd party libraries (such as AFNetworking, Alamofire or else), UIWebViews, and more.

Networking brings together URLSession, async-await (or Combine ), Decodable and Generics to simplify connecting to a JSON API. By providing a lightweight client that automates boilerplate code everyone has to write. By exposing a delightfully simple API to get the job done simply, clearly, and quickly. Getting swift models from a JSON API is now a problem of the past.

Declarative HTTP networking, designed for SwiftUI. swift-request can be installed via the Swift Package Manager. Once you've built your Request, you can specify the response handlers you want to use. .onData, .onString, .onJson, and .onError are available. You can chain them together to handle multiple response types, as they return a modified version of the Request. The body of the Request is built using the RequestBuilder @resultBuilder. It merges each RequestParam in the body into one CombinedParam object. This contains all the other params as children. When you run .call(), the children are filtered to find the Url, and any other optional parameters that may have been included.
