Get

A lean Swift web API client built using async/await.

Get provides a clear and convenient API for modeling network requests using Request<Response> type. And its APIClient makes it easy to execute these requests and decode the responses.

// Create a client
let client = APIClient(baseURL: URL(string: "https://api.github.com"))

// Start sending requests
let user: User = try await client.send(Request(path: "/user")).value

var request = Request(path: "/user/emails", method: .post, body: ["alex@me.com"]
try await client.send(request)

The client uses URLSession for networking and provides complete access to all its APIs. It is designed with the “less is more” idea in mind and doesn’t introduce any unnecessary abstractions on top of native APIs.

// In addition to `APIClientDelegate`, you can also override any methods
// from `URLSessionDelegate` family of APIs.
let client = APIClient(baseURL: URL(string: "https://api.github.com")) {
    $0.sessionDelegate = ...
}

// You can also provide task-specific delegates and easily change any of
// the `URLRequest` properties before the request is sent.
let delegate: URLSessionDataDelegate = ...
let response = try await client.send(Paths.user.get, delegate: delegate) {
    $0.cachePolicy = .reloadIgnoringLocalCacheData
}

In addition to sending quick requests, it also supports downloading data to a file, uploading from a file, authentication, auto-retries, logging, and more. It’s a kind of code that you would typically write on top of URLSession if you were using it directly.

Integrations

Pulse

You can easily add logging to your API client using Pulse. It requests a single line to setup.

let client = APIClient(baseURL: URL(string: "https://api.github.com")) {
    $0.sessionDelegate = PulseCore.URLSessionProxyDelegate()
}

With Pulse, you can inspect logs directly on your device – and it supports all Apple platforms. And you can share the logs at any time and view them on a big screen using Pulse Pro.

CreateAPI

With CreateAPI, you can take your backend OpenAPI spec, and generate all of the response entities and even requests for Get APIClient.

generate api.github.yaml --output ./OctoKit --module "OctoKit"

Check out App Store Connect Swift SDK that uses CreateAPI for code generation.

Other Extensions

Get is a lean framework with a lot of flexibility and customization points. It makes it very easy to learn and use, but you’ll need to install additional modules for certain features.

Mocker – mocking network requests for testing purposes
URLQueryEncoder – URL query encoder with Codable support
MultipartFormDataKit – adds support for multipart/form-data
NaiveDate – working with dates without timezones
