ASNetworkKit

A lightweight, Alamofire-inspired networking package built on top of URLSession, written in Swift.

• Request building (GET/POST/PUT/PATCH/DELETE/HEAD)
• Query & JSON parameter encoding
• Request adapters & interceptors
• Automatic retry policy (exponential backoff)
• Validation by status code & content type
• Response serialization: Data, String, JSON, Decodable
• File upload (data, file URL, multipart/form-data)
• File download with resume support
• Async/Await and callback APIs
• Reachability-independent design

Installation (Swift Package Manager)

In Xcode: File → Add Packages... and use the URL-https://github.com/arindam94/ASNetworkKit.git of this package.

Quick Start

import ASNetworkKit

let session = Session.default

// Simple GET
let request = session.request(
    "https://httpbin.org/get",
    method: .get,
    parameters: ["page": 1, "q": "swift"],
    encoding: URLEncoding.default
).validate()

request.responseDecodable(of: HTTPBinGet.self) { result in
    switch result {
    case .success(let model):
        print(model)
    case .failure(let error):
        print(error)
    }
}

Async/Await

struct User: Decodable { let id: Int; let name: String }

let session = Session.default
let user: User = try await session
    .request("https://jsonplaceholder.typicode.com/users/1")
    .serializingDecodable(User.self)
    .value
print(user.name)

Upload (multipart)

let data = Data("hello".utf8)
let req = session.upload(
    multipart: MultipartFormData() { form in
        form.append("Arindam", name: "author")
        form.append(data, name: "file", fileName: "hello.txt", mimeType: "text/plain")
    },
    to: "https://httpbin.org/post"
)
req.validate().responseJSON { print($0) }

Download

let destination = FileManager.default.temporaryDirectory.appendingPathComponent("file.bin")
let task = session.download("https://speed.hetzner.de/100MB.bin", to: destination)
let url = try await task.serializingDownloadedFile().value
print("Saved to:", url)
