A Concise HTTP Framework in Swift.


NetKit requires Swift 3.0 and Xcode 8.0.

There is a swift2 branch that supports Swift 2.3 and Xcode 7.3 if you’re not ready to upgrade to Swift 3.



Carthage is a decentralized dependency manager that builds your dependencies and provides you with binary frameworks.

You can install Carthage with Homebrew using the following command:

$ brew update
$ brew install carthage

To integrate NetKit into your Xcode project using Carthage, specify it in your Cartfile:

github "azizuysal/NetKit"

Run carthage update to build the framework and drag the built NetKit.framework into your Xcode project.


You can use CocoaPods to integrate NetKit with your project.

Simply add the following line to your Podfile:

pod "NetKit"

And run pod update in your project directory.


You can integrate NetKit manually into your project simply by dragging NetKit.framework onto Linked Frameworks and Libraries section in Xcode.


In order to run the included example project, you can install JSON Server. It provides a quick backend for prototyping and mocking on your local machine. A sample db.json file is included in the example project.

Use WebService to create a client for a particular web service and use it to make requests and process responses.

import NetKit

let service = WebService(urlString: "http://localhost:3000/")
  .responseJSON { json in
    return .Success
  .responseError { error in

responseJSON() is a convenience method and combines obtaining a response and converting to JSON into one step. You can also use response() method to obtain raw response data.

.response { data, response in
  print(String(data: data!, encoding: NSUTF8StringEncoding))
  return .Success

You can return .Success or .Failure(ErrorType) from the response handlers to signal error status and control will transfer to .responseError() in case of an error.

Synchronous Requests

You can use resumeAndWait() in order to make a synchronous request.

  .responseJSON { json in
    return .Success
  .responseError { error in

Authentication and SOAP support

If you need to set additional parameters, headers or authentication handlers, you can do so with Swift method chaining.

  .authenticate { (method, completionHandler) -> WebTaskResult in
    switch method {
    case .Default, .HTTPBasic:
      completionHandler(.UseCredential, NSURLCredential(user: loginId, password: password, persistence: .ForSession))
      completionHandler(.PerformDefaultHandling, nil)
    return .Success
  .setSOAP("<GetCitiesByCountry xmlns="http://www.webserviceX.NET"><CountryName>(country)</CountryName></GetCitiesByCountry>")
  .response { data, response in
    print(String(data: data!, encoding: NSUTF8StringEncoding))
    return .Success
  .responseError { error in

Support For All Configurations and Task Types

You can easily create WebService instances based on ephemeral or background sessions (the default is based on .defaultSessionConfiguration()).

let service = WebService(urlString: baseURL, configuration: .ephemeralSessionConfiguration())

Just as easily, you can create upload or download tasks (the default is data task).

let task = webService.GET("resource", taskType: WebTask.TaskType.Download)

Background Downloads

You can easily setup a background url session and create file download tasks.

let webService: WebService = {
  let configuration = NSURLSessionConfiguration.backgroundSessionConfigurationWithIdentifier("com.azizuysal.netkit.test")
  configuration.requestCachePolicy = .ReloadIgnoringLocalAndRemoteCacheData
  let service = WebService(urlString: baseURL, configuration: configuration)
  return service

You can use the convenient file download handler responseFile() to process downloaded files.

  .responseFile { (url, response) in
    let path = NSFileManager.defaultManager().URLsForDirectory(.DocumentDirectory, inDomains: .UserDomainMask).first?
    if let url = url, response = response, filename = response.suggestedFilename, path = path?.URLByAppendingPathComponent(filename) {
      do {
        try NSFileManager.defaultManager().copyItemAtURL(url, toURL: path)
      } catch let error as NSError {
        return .Failure(error)
    } else {
      return .Failure(WebServiceError.BadData("Bad params"))
    notifyUser(DownloadService.FileDownloaded, filename: response?.suggestedFilename)
    return .Success
  }.responseError { error in
    print((error as NSError).localizedDescription)
    notifyUser(DownloadService.FileDownloaded, error: error)
