After taking a look at the api you're using: The api expects for the data value to be a string and not an object. You'll need to do something like this: But this can be refactored to be much cleaner, this is just to explain whats going on.

Create data params:

let data: Parameters = [
    "username": "\(textFieldUserName.text!)",
    "pass": "\(textFieldPassword.text!)"
]

then convert it to a string: below is a quick search to convert json to string, but you'll need to double check that, as I took the first answer.

let string = stringify(json: data, prettyPrinted: false)

let parameters: Parameters = [
    "data": string
]

and in the request set the encoding to: encoding: URLEncoding.default

Alamofire.request(
        loginURL,
        method: .post,
        parameters: parameters,
        encoding: URLEncoding.default,
        headers: nil).responseJSON { (responseData) -> Void in
            if responseData.result.value != nil {
                //do something with data
    }
}

func stringify(json: Any, prettyPrinted: Bool = false) -> String {
    var options: JSONSerialization.WritingOptions = []
    if prettyPrinted {
        options = JSONSerialization.WritingOptions.prettyPrinted
    }

    do {
      let data = try JSONSerialization.data(withJSONObject: json, options: options)
      if let string = String(data: data, encoding: String.Encoding.utf8) {
          return string
      }
    } catch {
          print(error)
    }
    return ""
}

I would also try to avoid force unwrapping the textfield.text properties, unless you're validating their values somewhere else before hand and since the api call is http, you also need to enabled that in info.plist:

<key>NSAppTransportSecurity</key>
    <dict>
        <key>NSAllowsArbitraryLoads</key>
        <true/>
    </dict>

You should use Alamofire.request function with definition contains parameters: Parameters one. Like below.

Alamofire.request(.POST, "http://localhost:3030/", headers: [ACCESS_TOKEN:token, "Content-Type":"application/x-www-form-urlencoded"  ],
        parameters:["formData2" : formblabla, "formData1" : formblabla],
        encoding: .URL).response(completionHandler: {
            (request, response, data, error) in
        })

And there is the another fix to do for your question:

You set the your data in postman wrongly

The format is { "username": "blabla", "pass": "xxx" } is completely wrong.

Search for documenation of post data for Postman

You've to put all of the attributes separately as Key-Value pair.

parameter like `["formData2" : formblabla, "formData1" : formblabla]` is not working. – Abhishek Mitra Sep 30 '19 at 16:20
can you describe your parameters like this `let parameters: Parameters = [ "test": "123" ]` – eemrah Sep 30 '19 at 16:21
yes i did the same, and it require those curly brace. – Abhishek Mitra Sep 30 '19 at 16:22
did you use `response` or `responseJSON`for the getting response block? Can you try `responseJSON` if you've not use it. – eemrah Sep 30 '19 at 16:24
responseJSON, what i'm using there. – Abhishek Mitra Sep 30 '19 at 16:28
Updated the question. you can see now. – Abhishek Mitra Sep 30 '19 at 16:52
@AbhishekMitra I think I solve your problem, check my updated answer, you send your data wrongly in Postman. try it with key-pair and get result, then compare it with your response on Alamofire. – eemrah Sep 30 '19 at 20:20
there is a key `data` – Abhishek Mitra Sep 30 '19 at 20:29
use www-form-urlencoded and set each value for each key for example a value for username and other value for pass key – eemrah Sep 30 '19 at 20:38
I tried so many thing, but I failed every time. And above code is backdated I found that too. – Abhishek Mitra Sep 30 '19 at 20:40
I guess its older versions of the Alamofire, there are something to change for example encoding and method type. You can found out in github.com/Alamofire – eemrah Sep 30 '19 at 20:42
Thanks though, I'm trying. – Abhishek Mitra Sep 30 '19 at 20:42

You can use dictionary

let parameters = ["username": "xxxxx", "pass":"xxx"]

 Alamofire.request(YOURURL, method: .post, parameters: parameters, encoding: JSONEncoding.default, headers:nil ).responseJSON { response in
        switch response.result {
        case .success:
            let result = response.result.value
            let json = result as Dictionary
            print(json)
        case .failure(let error):
            let responseString = String(data: response.data, encoding:.utf8)
        }
