Alamofire: How to use a Proxy Server with Alamofire

[davidseek]

I'm trying to use my Proxy for an API request that needs a specified IP.
To debug my issue, I'm requesting the IP from a webservice.

This is my current code:

    import UIKit
    import Alamofire

    class ViewController: UIViewController {

        var requestManager = Alamofire.SessionManager.default

        override func viewDidLoad() {
            super.viewDidLoad()
        }

        override func viewDidAppear(_ animated: Bool) {
            super.viewDidAppear(true)

            var proxyConfiguration = [NSObject: AnyObject]()
            proxyConfiguration[kCFNetworkProxiesHTTPProxy] = "http://[email protected]" as AnyObject?
            proxyConfiguration[kCFNetworkProxiesHTTPPort] = "9293" as AnyObject?
            proxyConfiguration[kCFNetworkProxiesHTTPEnable] = 1 as AnyObject?

            let cfg = Alamofire.SessionManager.default.session.configuration
            cfg.connectionProxyDictionary = proxyConfiguration

            let ip = URL(string: "https://api.ipify.org?format=json")

            requestManager = Alamofire.SessionManager(configuration: cfg)
            requestManager.request(ip!).response { response in
                print("Request: \(response.request)")
                print("Response: \(response.response)")
                print("Error: \(response.error)")

                if let data = response.data, let utf8Text = String(data: data, encoding: .utf8) {
                    print("Data: \(utf8Text)")
                }
            }
        }
    }

The problem: the responsed IP is the same with or without the proxyConfiguration. Any help is very appreciated.

PS: physical device used.

As you can read here, this should be on Stack Overflow.

@davidseek You need to setup your URLSessionConfiguration by creating a new instance. Modifying values on the current configuration doesn't have any effect, as per Apple's documentation. In the future, you should open questions like this on Stack Overflow and tag alamofire.

Cheers. 🍻
