SwiftEndpoint is a lightweight library providing higher level of abstraction for implementing networking in iOS and macOS applications.

🛠 Tech stack

📝 Description

Endpoint is a generic function that transforms some Request into some Response publisher:

typealias Endpoint<Request, Response> = (Request) -> AnyPublisher<Response, Error>

🧩 Foundation URL networking

Set of helpers for building API clients based on the native Foundation's networking.

urlEndpoint function creates an Endpoint that uses Foundation's networking:

func urlEndpoint<Request, Response>(
  requestFactory: @escaping URLRequestFactory<Request>,
  publisherFactory: @escaping URLResponsePublisherFactory,
  responseValidator: @escaping URLResponseValidator,
  responseDecoder: @escaping URLResponseDecoder<Response>
) -> Endpoint<Request, Response>

URLRequestFactory<Request> is a generic function that transforms some Request into URLRequest, optionally throwing an error:

typealias URLRequestFactory<Request> = (Request) throws -> URLRequest

URLResponsePublisherFactory is a function that transforms URLRequest into URLResponsePublisher:

typealias URLResponsePublisherFactory = (URLRequest) -> URLResponsePublisher

Convenience extension allows to use URLSession as a URLResponsePublisherFactory:

extension URLSession {
  var urlResponsePublisherFactory: URLResponsePublisherFactory { get }

URLResponsePublisher is a combine publisher emitting network responses or failing with networking error:

typealias URLResponsePublisher = AnyPublisher<(data: Data, response: URLResponse), Error>

URLResponseValidator is a function that validates response Data and URLResponse, optionally throwing validation error:

typealias URLResponseValidator = (Data, URLResponse) throws -> Void

URLResponseDecoder<Response> is a generic function that transforms response Data and URLResponse into some Response, optionally throwing decoding error:

typealias URLResponseDecoder<Response> = (Data, URLResponse) throws -> Response
