Alamofire response coming but the same is not coming in "Success case" why? in swift

Question

Json response is coming but which is not coming in Alamofire Success case why?

Code: I am using Alamofire in APIReqeustManager Class, and calling its service call in login swift file... so here Json response is coming but which is not coming in Alamofire Success case why?

typealias requestCompletionHandler = (APIJSONReponse) -> Void

class APIReqeustManager: NSObject {

static let sharedInstance = APIReqeustManager()

 func serviceCall(param:[String:Any]?,
             method : HTTPMethod,
             loaderNeed : Bool,
             isTokenNeeded : Bool,
             header : [String : String]? = nil,
             url: String
             completionHandler:@escaping requestCompletionHandler) {

let params  = ["jsonrpc" : "2.0", "params" : param ?? nil] as [String : Any?]


sendRequestWithURL(url, method: method, needViewHideShowAfterLoading: needViewHideShowAfterLoading, queryParameters: queryParam, bodyParameters: (param != nil) ? (params as [String : AnyObject]?) : nil, headers: [String : String].self as? [String : String], vc: vc){
    resp in
    print(resp.response ?? "COULDN'T PARSE: \(String(data: resp.data ?? Data(), encoding: .utf8) ?? "")")

    ....
    
}


fileprivate func sendRequestWithURL(_ URL: String,
                                method: HTTPMethod,
                                retryCount: Int = 0,
                                completionHandler:@escaping 
requestCompletionHandler) {

let actualURL: String

var headerParams: HTTPHeaders?

if let headers = headers {
    headerParams = headers as? HTTPHeaders
}
print(headerParams)
print("Actual URL \(actualURL)")

AF.request(actualURL, method:method, parameters: bodyParameters,encoding: JSONEncoding.default, headers: headerParams)
    .responseJSON { response in

        print("Json response \(response)")//response coming
        switch response.result {
        case .success:
            let JSON = response.result as? NSDictionary
                print("JSON inside success: \(JSON)")//nil

                let wrappedResponse = APIJSONReponse.init(
                    data: response.data,
                    dict: response.result as! Dictionary<String, AnyObject>,//Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)
                    response: response.response,
                    error: nil, rpcErrorData: nil)
                DispatchQueue.main.async(execute: {
                    completionHandler(wrappedResponse)
                })
        case .failure(let error):
            let error = error
            let wrappedResponse = APIJSONReponse.init(error: error, dataDict: [:])
            completionHandler(wrappedResponse)
            print(error.localizedDescription)
        }
}
}
}

and now calling this in login swift file like below

 func loginService() {

        let param = ["email" : "[email protected]",
                     "password": "12345678"]
        APIReqeustManager.sharedInstance.serviceCall(param: param, method: .post, url: "http://test.com/dev/login", isTokenNeeded: false){ [weak self] (resp) in
            
            print("login response \(resp)")

        }
    }

out put:

with above code if i print print("Json response: \(response)") the the response will be like this

Json response: success({
result =     {
    status = A;
    token = "testtttttttt";
    userdata =         {
        "available_for_serivice" = N;
        "buy_review" = "<null>";
        city = test city;
        "company_name" = test;
       

for the same success response if i print inside Success case then print("JSON inside success: (JSON)")

nil

Thread 1: EXC_BAD_INSTRUCTION (code=EXC_I386_INVOP, subcode=0x0)

Edit: its like this

class APIJSONReponse {
let data: Data?
let dict: Dictionary<String, AnyObject>?
let response: URLResponse?
var error: Error?
var message : String?
var rpcErrorData: ErrorDataModel?

init(response: URLResponse?,error: Error?,rpcErrorData: ErrorDataModel?){
