Send multiple array in parameter in swift - ios

Question

I'm calling a service in which I'm trying to send parameter that consist of array within an array and other parameters which are outside from an array. The format in which I have to send parameter is this:
{
"RestID": 0,
"cart": [
{
"childs": [
{
"addon_cat_id": 0,
"id": 0,
"name": "string",
"next_move_id": 0,
"price": 0,
"sort_order": 0,
"type": "string"
}
],
"name": "string",
"price": "string",
"productid": 0,
"qty": 0,
"description": "string"
}
],
"coupon_code": "string",
"coupon_type": "string",
"coupon_value": 0,
"delivery_price": "string",
"discount_amount": "string"
}
This is how I'm sending my parameter in the service:
let parameter:[String:Any] = ["RestID":restaurantId!,
"cart":[["childs":["addon_cat_id":"0",
"id":ItemDataSource.sharedInstance.items[0].itemId!,
"name":ItemDataSource.sharedInstance.items[0].itemName!,
"next_move_id":"",
"price":ItemDataSource.sharedInstance.items[0].itemPrice!,
"sort_order":"",
"type":"string"
]],
["name": ItemDataSource.sharedInstance.items[0].itemName!,
"price": ItemDataSource.sharedInstance.items[0].itemPrice!,
"productid": ItemDataSource.sharedInstance.items[0].itemId!,
"qty": 2,
"description":ItemDataSource.sharedInstance.items[0].itemDdescription!]
],
"coupon_code" : couponCode!,
"coupon_type" : couponType!,
"coupon_value" : couponValue!,
"delivery_price" : deliveryLbl.text!,
"discount_amount" : disocunt!,
"discount_description" : discountDesc!,
"discount_info" : discountInfo!,
"distance": "",
"door_num" : doorTxt.text!,
"firstname" : "",
"lastname" : "",
"order_type" : "Delivery",
"payment_mode" : "",
"phone" : mobileTxt.text!,
"postcode" : postCodeTxt.text!,
"preorder" : true,
"preorder_is_preorder" : "",
"street" : address1Txt.text!,
"token" : "",
"town" : addressTxt2.text!,
"total": self.grandTotalLbl.text!,
"stripeToken" : "",
"customer_id" : "2",
"preordertime": preOrderTime,
"usercmt": "descri",
"email": userEmail!
]
But when I call the service I get an error. I have discussed this with the server side and they are saying it is a mistake in sending the parameter. How can I send multiple arrays within an array in parameter?
This is my service class:
class SaveOrderDeliveryService{
static let instance = SaveOrderDeliveryService()
var status:Int = 0
func saveOrderDelivery(param:[String:Any],completion:#escaping CompletionHandler) {
Alamofire.request(saveOrderDeliveryUrl, method: .post, parameters:param, encoding: JSONEncoding.default, headers: nil).responseJSON { (response) in
print("Request: \(String(describing: response.request))") // original url request
print("Response: \(String(describing: response.response))") // http url response
print("Result: \(response.result)")// response serialization result
print(response)
if response.result.error == nil{
self.status = (response.response?.statusCode)!
if(self.status == 200){
print(response)
guard let data = response.data else {return}
do{
if let json = try JSON(data: data).dictionary{
completion(true)
}
}catch let jsonErr{
print(jsonErr)
}
}
completion(true)
}else{
completion(false)
debugPrint(response.result.error as Any)
}
}
}
}
