An awesome Swift HTTP library to rapidly create communication layers with API endpoints.


You can simply use SwiftHttp as a dependency via the Swift Package Manager:

.package(url: "https://github.com/binarybirds/swift-http", from: "1.0.0"),

Add the SwiftHttp product from the swift-http package as a dependency to your target:

.product(name: "SwiftHttp", package: "swift-http"),

Import the framework:

import SwiftHttp

That's it.

Basic usage

It is really easy to setup a communication layer with an API endpoint.

import SwiftHttp

struct Todo: Codable {
    let id: Int
    let title: String
    let completed: Bool

struct TodoApi: HttpCodablePipelineCollection {

    let client: HttpClient = UrlSessionHttpClient(logLevel: .info)
    let apiBaseUrl = HttpUrl(host: "jsonplaceholder.typicode.com")

    func list() async throws -> [Todo] {
        try await decodableRequest(
            executor: client.dataTask,
            url: apiBaseUrl.path("todos"),
            method: .get

// api usage
let todos = try await api.list()

// curl log
// curl "https://jsonplaceholder.typicode.com/todos/"

The HttpClient provides the executors to perform data, download or upload tasks.

You can create decodable, encodable, codable or raw request when using a codable pipeline collection.

Using raw requests & responses

You can create raw HTTP requests using the HttpUrl and the HttpRawRequest type.

let url = HttpUrl(
    scheme: "https",
    host: "jsonplaceholder.typicode.com",
    port: 80,
    path: ["todos"],
    resource: nil,
    query: [:],
    fragment: nil

let req = HttpRawRequest(
    url: url, 
    method: .get, 
    headers: [:], 
    body: nil

/// execute the request using the client
let client = UrlSessionHttpClient(session: .shared, logLevel: .info)
let response = try await client.dataTask(req)

/// use the response data
let todos = try JSONDecoder().decode([Todo].self, from: response.data)
// response.statusCode == .ok
// response.headers -> response headers as a dictionary

You can use a specific HttpClient to execute a request using a data, download or upload task.

Constructing URLs

The HttpUrl type allows us to construct various URLs using a base URL.

let baseUrl = HttpUrl(host: "jsonplaceholder.typicode.com")

// https://jsonplaceholder.typicode.com/todos/

// https://jsonplaceholder.typicode.com/todos/1/
baseUrl.path("todos", String(1))    

// https://jsonplaceholder.typicode.com/todos/?foo=bar
baseUrl.path("todos").query("foo", "bar")

// https://jsonplaceholder.typicode.com/todos/?foo=baz&bar=1
    "foo": "baz",
    "bar": "1",

You can transform a HttpUrl object into a Foundation URL by using the .url property.


You can create a raw request object using a HttpUrl and a HttpMethod, including additional headers and a body data.

let url = HttpUrl(host: "localhost", path: ["login"])

let token: String = "valid-token"
let body = try JSONEncoder().encode([
    "foo": "bar",
let req = HttpRawRequest(
    url: url,
    method: .post,
    headers: [
        .key(.authorization): "Bearer \(token)",
        .custom("my-header"): "my-header-value",
    body: body

curl "https://localhost/login/" \
    -X POST \
    -H 'my-header: my-header-value' \
    -H 'Authorization: Bearer valid-token' \
    -d '{"foo":"bar"}'

You can transform a HttpRequest into a URLReequest via the .urlRequest property. You can print the cURL representation of a request by using the .curlString property on a URLRequest object.

Response validation

You can validate a response by using a HttpResponseValidator object.

// mock response
let response = HttpRawResponse(
    statusCode: .ok,
    headers: [
        .key(.contentType): "application/json",
    data: .init()

// check if the status code is between 200 and 299               
let validator1 = HttpStatusCodeValidator() // -> (.ok), (.notFound), etc.
try validator1.validate(response)

// check if a header key exists and the value is equal to "application/json"
let validator2 = HttpHeaderValidator(.key(.contentType)) { value in
    value == "application/json"

try validator2.validate(response)

// validate using multiple validators
let validation = HttpResponseValidation([validator1, validator2])
try validation.validate(response)

It is possible to check for multiple validation criterias using a HttpResponseValidation.


A pipeline allows you to transform a raw request and a raw response using a set of custom actions.

You can create your own HttpRequestTransformer object to add extra headers to your request and encode a custom body object to a data value.

You can create your own HttpResponseTransformer object to validate the response and decode a custom value from the response data.

The codable (encodable, decodable, codable) pipelines are a good example of this approach.
