Sending JSON object as a post parameter using Alamofire - ios

Question

I'm currently working on an iOS app, and recently I faced an obstacle, basically the API endpoint I'm trying to consume requires a JSON object as a POST parameter in this format.
{
json: {
product_report: [
{
"id_assigned_pos": someid,
"id_user": someid,
"number": somenumber,
},
{
"id_assigned_pos": someid,
"id_user": someid,
"number": somenumber,
},{
"id_assigned_pos": someid,
"id_user": someid,
"number": somenumber,
}
]
}
}
I'm having a hard time figuring out how to achieve this using Alamofire and swift 4.
I'd appreciate someone's help.
Thanks!

let parameters = [
"json": [
"product_report": [
[
"id_assigned_pos": 1,
"id_user": 1,
"number": 1
],
[
"id_assigned_pos": 1,
"id_user": 1,
"number": 1
],
[
"id_assigned_pos": 1,
"id_user": 1,
"number": 1
],
]
]
]
Alamofire.request(url, method:.post, parameters:parameters, headers:headers).responseJSON { response in
// Here is the response
} `

You can try this one:
var dict : [String: Any] = [:]
dict["type"] = "Step"
dict["data"] = ["2015-08-02": 8574];
let params: [String: Any] = ["r_id": "someName",
"data": String.jsonString(data: dataDict)];
Here jsonString is an extension of String
static func jsonString(data : Any) -> String {
var jsonString = "";
do {
let jsonData = try JSONSerialization.data(withJSONObject: data, options: .prettyPrinted)
jsonString = NSString(data: jsonData, encoding: String.Encoding.utf8.rawValue)! as String
} catch {
print(error.localizedDescription)
}
return jsonString;
}
