What is AFNetworking?

AFNetworking is a popular networking library for iOS and macOS applications. It provides a comprehensive set of networking and reachability features, making it easy to handle tasks such as making HTTP requests, downloading files, and managing network connectivity.


To use AFNetworking in your iOS or macOS project, follow these steps:

  1. Open your project in Xcode.
  2. Open the terminal and navigate to your project directory.
  3. Run the following command to install AFNetworking using CocoaPods:
pod 'AFNetworking'

This will add the AFNetworking dependency to your project. Make sure to remember to use the .xcworkspace file instead of the .xcodeproj file from now on.

Getting Started

Once you have successfully installed AFNetworking, you can start using it in your project. Here’s a quick overview of how to get started:

Importing AFNetworking

You’ll need to import the AFNetworking headers in the files where you want to use it. Usually, this would be in your view controllers or network manager classes. Add the following line at the top of your file:

import AFNetworking

Making a GET Request

To make a simple GET request, use the following code snippet:

// Create a session manager
let manager = AFHTTPSessionManager()

// Make the GET request
manager.get("", parameters: nil, headers: nil, progress: nil) { (task, response, error) in
    if let error = error {
        // Handle the error
        print("Error: \(error.localizedDescription)")
    } else if let response = response {
        // Handle the response
        print("Response: \(response)")

Advanced Usage

AFNetworking provides a wide range of features and customization options. Here are some of the advanced topics you might need:

Downloading Files

AFNetworking makes it easy to download files from a remote server. Use the following code example:

// Destination file URL
let destination = DownloadRequest.suggestedDownloadDestination(for: .documentDirectory)

// Download the file"", to: destination).response { response in
    if let error = response.error {
        // Handle the error
        print("Error: \(error.localizedDescription)")
    } else if let url = response.destinationURL {
        // Handle the downloaded file URL
        print("Downloaded file: \(url)")

Handling Authentication

If your server requires authentication, you can easily include the necessary credentials in your requests. Use the following code snippet as a starting point:

// Set the authentication credentials
let username = "your_username"
let password = "your_password"
manager.requestSerializer.setAuthorizationHeaderFieldWithUsername(username, password: password)

// Make the authenticated request
manager.get("", parameters: nil, headers: nil, progress: nil) { (task, response, error) in
    // Handle the response
