Try this: Using Custom Encoding

 struct JSONStringArrayEncoding: ParameterEncoding {
    private let array: [[String : Any]]

    init(array: [[String : Any]]) {
        self.array = array
    }

    func encode(_ urlRequest: URLRequestConvertible, with parameters: Parameters?) throws -> URLRequest {
        var urlRequest = try urlRequest.asURLRequest()

        let data = try JSONSerialization.data(withJSONObject: array, options: [])

        if urlRequest.value(forHTTPHeaderField: "Content-Type") == nil {
            urlRequest.setValue("application/json", forHTTPHeaderField: "Content-Type")
        }

        urlRequest.httpBody = data

        return urlRequest
    }
}

Calling

let values  = [
            [
                "fieldName" : "abc",
                "fieldValue":"xyz"
            ],
            [
                "fieldName" : "123",
                "fieldValue":"789"
            ]
        ]

        let param  =  [
            "page":"1",
            "size":"5",
            "sortBy":"profile_locality"
        ]

        let parameterEncoding = JSONStringArrayEncoding.init(array: values)

        Alamofire.request("url", method: .post, parameters: param, encoding:parameterEncoding  ).validate().response { (responseObject) in
            // do your work
        }
