How do I use JSON arrays with Alamofire parameters?

I'm having a bit of trouble structuring my parameters so that our server API would be able to read it as valid JSON.

Alamofire uses parameters like this in swift language

let parameters : [String: AnyObject] =
[
    "string": str
    "params": HOW I INSERT A VALID JSON ARRAY HERE
]

The problem is that AnyObject does not seem to accept JSON so how would I send / create a structure like this with swift?

{
"string": str, "params" : [
    {
        "param1" : "something",
        "param2" : 1,
        "param3" : 2,
        "param" : false
    },
    {
        "param1" : "something",
        "param2" : 1,
        "param3" : 2,
        "param" : false
    }]
}

Using Swift 5 You can use like this.

  var authParams:[String:Any] = [:]

  var authParamsObject:[String:Any] = [:]


    authParamsObject["is_urgent"] = data_any
    authParamsObject["body"] = data_any

  authParams = ["note_set" : authParamsObject]

Json Result :

{
  "note_set":
    {
      "is_urgent": true,
      "body": "string"
    }
}

In case, there is a need to pass array directly as a parameter for a alamofire request, the following method worked for me.

source: https://github.com/Alamofire/Alamofire/issues/1508 

let headers = NetworkManager.sharedInstance.headers
var urlRequest = URLRequest(url: URL(string: (ServerURL + Api))!)
urlRequest.httpMethod = "post"
urlRequest.allHTTPHeaderFields = headers
let jsonArrayencoding = JSONDocumentArrayEncoding(array: documents)
let jsonAryEncodedRequest = try? jsonArrayencoding.encode(urlRequest, with: nil)

    var request: Alamofire.DataRequest? = customAlamofireManager.request(jsonAryEncodedRequest!)
    request?.validate{request, response, data in
        return .success
        }
        .responseJSON {

Swift 2.2 and using SwiftyJSON.swift
You can use like this.

    var arrayList : [String: AnyObject]//one item of array

    var list: [JSON] = []//data array 

    for i in 0..<10//loop if you need
    { 

        arrayList = [
            "param1":"",
            "param1":"",
            "param2":["","",""]
        ]

        list.append(JSON(arrayList))//append to your list

    }


    //params
    let params: [String : AnyObject]=[

        "Id":"3456291",
        "List":"\(list)"//set
    ]

if you are using SwiftyJSON, you can write like this

let array = ["2010-12-13T5:03:20","2010-12-13T5:03:20"]
 let paramsJSON = JSON(array)
 var arrString = paramsJSON.rawString(NSUTF8StringEncoding)

You need to create a NSArray object for array parameters.

var yourParameters = [
  "String": "a string",
  "Int": 1,
  "Array": NSArray(
    array: [
        "a", "b", "c"
    ])
]

Solved this myself. I can just do

    parameters =
    [
        "params": array
    ]

Where array is Dictionary (String, AnyObject). The problem I initially had with this solution was that you can't insert booleans into this kind of dictionary, they will just be converted into integers. But apparently alamofire JSON encoding (I think) sends them as true/false values nevertheless.

Taken from Alamofire's GitHub page:

let parameters = [
    "foo": [1,2,3],
"bar": [
    "baz": "qux"
]
]

Alamofire.request(.POST, "http://httpbin.org/post", parameters: parameters, encoding: .JSON)
// HTTP body: {"foo": [1, 2, 3], "bar": {"baz": "qux"}}

EDIT: And from your example:

let parameters = [
    "string": "str",
"params": [[
    "param1" : "something",
    "param2" : 1,
    "param3" : 2,
    "param" : false
],[
    "param1" : "something",
    "param2" : 1,
    "param3" : 2,
    "param" : false
]
]
]
