**It was solved by using SwiftyJson. I searched many sites but I did not get expected answer. I am posting the answer because it will be useful for someone

Solution is

I tried to post key value in dictionary format instead of json format,That's why i did not get expected output. swiftjson is very to write json object.**

let emptyJson : JSON = JSON(["customer_id":"26",
                                 "totalcost":"8500",
                                 "delivery_type":"take_away",
                                 "order_name":"",
                                 "order_mobilenumber":"",
                                 "order_city":"Chose Your Place",
                                 "order_address":"",
                                 "take_away_time":" Next 2 Hour ",
                                 "":[
                                    [
                                        "parent_id":"145",
                                        "subitem_id":"179",
                                        "quentity":"1"
                                    ]
                                    ]
                               ])
let parameters: [String: Any] = [
        "data": emptyJson
    ]
Alamofire.request("http://_con",method:.post,parameters:parameters).responseJSON{response in
        let jsonResult = response.result.value
        print(jsonResult)

    }

And There is no need to use json encoding in Alamofire request.we just are posting json object.
