Write Requests Fast!

Alamofire's compact syntax and extensive feature set allow requests with powerful features like automatic retry to be written in just a few lines of code.

// Automatic String to URL conversion, Swift concurrency support, and automatic retry.
let response = await AF.request("https://httpbin.org/get", interceptor: .retryPolicy)
                       // Automatic HTTP Basic Auth.
                       .authenticate(username: "user", password: "pass")
                       // Caching customization.
                       .cacheResponse(using: .cache)
                       // Redirect customization.
                       .redirect(using: .follow)
                       // Validate response code and Content-Type.
                       .validate()
                       // Produce a cURL command for the request.
                       .cURLDescription { description in
                         print(description)
                       }
                       // Automatic Decodable support with background parsing.
                       .serializingDecodable(DecodableType.self)
                       // Await the full response with metrics and a parsed body.
                       .response
// Detailed response description for easy debugging.
debugPrint(response)

Component Libraries

In order to keep Alamofire focused specifically on core networking implementations, additional component libraries have been created by the Alamofire Software Foundation to bring additional functionality to the Alamofire ecosystem.

• AlamofireImage - An image library including image response serializers, UIImage and UIImageView extensions, custom image filters, an auto-purging in-memory cache, and a priority-based image downloading system.
• AlamofireNetworkActivityIndicator - Controls the visibility of the network activity indicator on iOS using Alamofire. It contains configurable delay timers to help mitigate flicker and can support URLSession instances not managed by Alamofire.

Known Issues on Linux and Windows

Alamofire builds on Linux, Windows, and Android but there are missing features and many issues in the underlying swift-corelibs-foundation that prevent full functionality and may cause crashes. These include:

• ServerTrustManager and associated certificate functionality is unavailable, so there is no certificate pinning and no client certificate support.
• Various methods of HTTP authentication may crash, including HTTP Basic and HTTP Digest. Crashes may occur if responses contain server challenges.
• Cache control through CachedResponseHandler and associated APIs is unavailable, as the underlying delegate methods aren't called.
• URLSessionTaskMetrics are never gathered.
• WebSocketRequest is not available.

Due to these issues, Alamofire is unsupported on Linux, Windows, and Android. Please report any crashes to the Swift bug reporter.
