Append multiple NSMutableArray data to another NSMutableArray in swift 3 - ios

Question

Let's say, there is shipping nsdictionary value is required to send to server, and there is items NSMutableArray inside shipping and, again there is sub-items NSMutableArray inside items.
That's why I've coded like that:
for cake in cakes {
for item in cakeItemsOpt {
let optionalItem = [
"item_req_mod_p_id": item.cakeItemModId,
"l_req_mod_p_id": item.cakeModId,
"mod_id": item.cakeModId,
"mod_qty": item.cakeQty
]
itemsOptional.add(optionalItem)
}
for item in cakeItemsReq {
let requiredItem = [
"item_req_mod_p_id": item.cakeItemModId,
"l_req_mod_p_id": item.cakeModId,
"mod_id": item.cakeModId,
"mod_qty": "1"
]
itemsRequired.add(requiredItem)
}
let cakeParam: NSDictionary = [
"id": cake.cakeId,
"qty": cake.cakeQty,
"type": cake.cakeType,
"name": cake.cakeName,
"image": cake.cakeImage,
"req_modifiers": itemsRequired,
"opt_modifiers": itemsOptional
]
items.add(cakeParam)
}
let param: NSDictionary = [
"user_id": user_id,
"token": token,
"delivery": "del",
"delivery_remark": delivery_remark,
"delivery_date": delivery_date,
"delivery_time": delivery_time,
"delivery_charge": delivery_charge,
"item": items,
"payment_method_id": payment_id,
] as [String : Any]
param is main object to send to server.
But the result is not what I've expected,
["delivery_remark": "heavy", "payment_method_id": "4", "delivery": "del", "token": "0l8BwedwkZQltcFYFhCpicQZeQOhikyYLxa8R3u2", "item": <__NSArrayM 0x60800044ea90>(
{
id = 11;
image = "";
name = "Red Velvet 16cm";
"opt_modifiers" = (
{
"item_req_mod_p_id" = 49;
"l_req_mod_p_id" = 3;
"mod_id" = 3;
"mod_qty" = "";
},
{
"item_req_mod_p_id" = 49;
"l_req_mod_p_id" = 4;
"mod_id" = 4;
"mod_qty" = "";
}
);
qty = 2;
"req_modifiers" = (
{
"item_req_mod_p_id" = 55;
"l_req_mod_p_id" = 8;
"mod_id" = 8;
"mod_qty" = 1;
},
{
"item_req_mod_p_id" = 56;
"l_req_mod_p_id" = 3;
"mod_id" = 3;
"mod_qty" = 1;
}
);
"run_no" = "6260-1c86";
"small_candles" = "";
"sponge_color_id" = "";
"theme_id" = "";
"theme_name" = "";
type = item;
"word_color_id" = "";
}
)
, "delivery_charge": "15.00", "user_id": "21", "delivery_time": "3", "delivery_date": "2017-02-27"]
There is <__NSArrayM 0x60800044ea90> included in my object. Please let me know how to correct my coding to get correct result. Thanks.

Answer 1

Then i guess you want something like
let data: [String : [String : [String : [String]]]]
data = [
"shipping" : ["items" : ["subitemKey" : ["subitemArray"]]]
]
So you have a dictionary that contains a dictionary for a key "shipping" that contains a dictionary for key "items" that contains arrays for keys of different subitems
