Set timeout in Alamofire

For new versions of AF, see https://stackoverflow.com/a/61192412/308315

For old versions, please try this:

    let request = NSMutableURLRequest(url: URL(string: "")!)
    request.httpMethod = "POST"
    request.setValue("application/json", forHTTPHeaderField: "Content-Type")
    request.timeoutInterval = 10 // 10 secs
    let values = ["key": "value"]
    request.httpBody = try! JSONSerialization.data(withJSONObject: values, options: [])
    Alamofire.request(request as! URLRequestConvertible).responseJSON {
        response in
        // do whatever you want here
    }

I have same problem too, I think I found the solution. Try to declare SessionManager?or in your case alamofireManager in class, outside the function

class ViewController: UIViewController {
   var alamoFireManager : SessionManager? // this line

   func alamofire(){
        let configuration = URLSessionConfiguration.default
        configuration.timeoutIntervalForRequest = 10
        configuration.timeoutIntervalForResource = 10
        alamoFireManager = Alamofire.SessionManager(configuration: configuration) // not in this line

        alamoFireManager.request("my_url", method: .post, parameters: parameters).responseJSON { response in


        switch (response.result) {
        case .success:
                 //Success....
            break
        case .failure(let error):
               // failure...
             break
       }
     }
   }

}

Alamofire 5.1 includes a new way to modify the request with a closure in the initializer:

AF.request(url) { $0.timeoutInterval = 60 }
    .validate()
    .response { _ in // handle response here }
