Alamofire: send parameter - ios

Question

I want to post data as parameter like this:
{
"data":
[
{
"nik" : "lalaal"
}
]
}
How do I write to these parameters in Swift 3 using Alamofire?
i tried :
let parameter: Parameters = [
"data":[[
"nik" : self.nik,
"check_type" : "IN",
"tanggal" : "01-08-2017 18:22:00",
"long" : String(locationList[projectChoosen].long!),
"lat" : String(locationList[projectChoosen].lat!),
"id_loc" : locationList[projectChoosen].id_project,
"id_project" : nil,
"nama_project" : locationList[projectChoosen].nama_project,
"barcode" : "",
"foto": "",
"mime_type" : "image/jpeg"
]]
]

You can use below code.
let dicRequest: NSDictionary = ["userid" : "test", "password" : "test123"]
let postParams:NSDictionary = [
"data": dicRequest
]
let requestURL: String = String(format: "%#/Login", serverURL)
Alamofire.request(requestURL, method: .post, parameters: postParams as? [String : AnyObject], encoding: JSONEncoding.default, headers: [:])
.responseJSON { response in switch response.result {
case .success(let JSON):
print("response :-----> ",response)
case .failure(let error):
print("Request failed with error: \(error)")
}
}

You can create a Dictionary object first in this formate
{
"data":
[
{
"nik" : "lalaal"
}
]
}
After that you can convert this using NSJSONSerlisation to json string
And than post using Almofire.
let array: [[String: String]] = [["nik": "lalaal"]]
let data = try JSONSerialization.data(withJSONObject: array, options: JSONSerialization.WritingOptions.prettyPrinted)
let string = String(data: data, encoding: String.Encoding.utf8)
let postParam: [String: String] = ["data": string]
let _ = Alamofire.request(apiType.url!, method: apiType.type!,parameters: postParam, encoding: JSONEncoding.prettyPrinted, headers: nil).validate(statusCode: 200..<500).responseJSON { (response) in
}

Answer 3

Here is a sample request using Alamofire and posting a dictionary as parameters:
let dataArray: [[String: String]] = [["nik": "lalaal"]]
let param: [String: [Any]] = ["data": dataArray]
Alamofire.request(url, method: .post, parameters: param, encoding: JSONEncoding.default, headers: nil).responseJSON { response in }

I use :
let dataIn: [String: String] = ["param1": "value1"]
let paramGo: [String: [String: String]] = ["data_title": dataIn]
Alamofire.request(url, method: .post, parameters: paramGo, encoding: JSONEncoding.default, headers: nil).responseJSON { response in }
