Set timeout in Alamofire

Question

I am using Alamofire 4.0.1 and I want to set a timeout for my request. I tried the solutions gived in this question:

In the first case

Answer 1

As Matt said the problem is the following

The difference here is that the initialized manager is not owned, and is deallocated shortly after it goes out of scope. As a result, any pending tasks are cancelled.

The solution to this problem was written by rainypixels

import Foundation import Alamofire

class NetworkManager {

    var manager: Manager?

    init() {
        let configuration = NSURLSessionConfiguration.defaultSessionConfiguration()
        manager = Alamofire.Manager(configuration: configuration)
    }
}

And my own version

class APIManager {

    private var sessionManager = Alamofire.SessionManager()

    func requestCards(_ days_range: Int, success: ((_ cards: [CardModel]) -> Void)?, fail: ((_ error: Error) -> Void)?) {
        DispatchQueue.global(qos: .background).async {
            let parameters = ["example" : 1]

            let headers = ["AUTH" : "Example"]

            let configuration = URLSessionConfiguration.default
            configuration.timeoutIntervalForRequest = 10
            self.sessionManager = Alamofire.SessionManager(configuration: configuration)

            self.sessionManager.request(URLs.cards.value, method: .get, parameters: parameters, encoding: URLEncoding.default, headers: headers).responseJSON { (response) in
                switch response.result {
                case .success:
                    //do json stuff
                    guard let json = response.result.value as? [String : Any] else { return }
                    guard let result = json["result"] as? [[String : Any]] else { return }
                    let cards = Mapper().mapArray(JSONArray: result)
                    debugPrint("cards", cards.count)
                    success?(cards)
                case .failure(let error):
                    if error._code == NSURLErrorTimedOut {
                        //timeout here
                        debugPrint("timeOut")
                    }
                    debugPrint("\n\ncard request failed with error:\n \(error)")
                    fail?(error)
                }
            }
        }
    }
}

Can also make a manager for it

import Alamofire

struct AlamofireAppManager {

    static let shared: SessionManager = {
        let configuration = URLSessionConfiguration.default
        configuration.timeoutIntervalForRequest = 10
        let sessionManager = Alamofire.SessionManager(configuration: configuration)
        return sessionManager
    }()

}
