Alamofire timeout not working - ios

Question

In my app I am using Alamofire for network request and I created a class. Here is the class
class MGNetworking: NSObject{
private class func getAlamofireManager() -> SessionManager {
let configuration = URLSessionConfiguration.default
configuration.timeoutIntervalForResource = 180 // seconds
configuration.timeoutIntervalForRequest = 180 // seconds
let alamofireManager = Alamofire.SessionManager(configuration: configuration)
return alamofireManager
}
class func requestGETURL(_ strURL: String, success:#escaping (JSON) -> Void, failure:#escaping (Error) -> Void) {
getAlamofireManager().request(strURL,method: .get).responseJSON { (responseObject) -> Void in
if responseObject.result.isSuccess {
let resJson = JSON(responseObject.result.value!)
success(resJson)
}
if responseObject.result.isFailure {
let error : Error = responseObject.result.error!
failure(error)
}
}
}
class func requestPOSTURL(_ strURL : String, params : [String : AnyObject]?, headers : [String : String]?, success:#escaping (JSON) -> Void, failure:#escaping (Error) -> Void){
getAlamofireManager().request(strURL, method: .post, parameters: params, encoding: URLEncoding.default, headers: headers).responseJSON { (responseObject) -> Void in
if responseObject.result.isSuccess {
let resJson = JSON(responseObject.result.value!)
success(resJson)
}
if responseObject.result.isFailure {
let error : Error = responseObject.result.error!
failure(error)
}
}
}
}
I want change timeout for my network request. I created method getAlamofireManager() but when I am calling this method my request cancelled here is the error.
FAILURE: Error Domain=NSURLErrorDomain Code=-999 "cancelled"
When I change getAlamofireManager() to Alamofire.request it is start working perfect.

I can make an assumption that issue is connected with this reported problem.
So lets rewrite code:
class MGNetworking: NSObject{
var manager: SessionManager?
init() {
manager = getAlamofireManager()
}
private class func getAlamofireManager() -> SessionManager {
let configuration = URLSessionConfiguration.default
configuration.timeoutIntervalForResource = 180 // seconds
configuration.timeoutIntervalForRequest = 180 // seconds
let alamofireManager = Alamofire.SessionManager(configuration: configuration)
return alamofireManager
}
}
So now use manager instead of the getAlamofireManager() for the requests
