                            ]
    
     let parameters: [String: Any] = [
                                
                                "firstName": atd1FirstName,

                            ]
    attendeeData.append(parameters)
    attendeeData.append(parameters2)        

    addAttendeeService(parameter: attendeeData)

    private func addAttendeeService(parameter: [String: Any]){
        DispatchQueue.global().async {
            AF.request("http://178.18.200.116:96/api/SessionPerson/Add",method: .post,parameters: parameter, encoding: JSONEncoding.default).response{ response in
            debugPrint(response)
    }

                let parameters: [String: Any] = [
                    
                    
                      {

Simply changed your { } into [] that will solve your issue.

  let parameters: [String: Any] = [
                
                
                  [
                      "firstName": atd1FirstName,
                      "lastName": atd1LastName,
                      "email": atd1Email,
                      "telNo": atd1Phone,
                      "nationality": atd1Nationatility,
                      "licenseNumber": atd1LicenseNumber,
                      "companyName": atd1CompanyName,
                      "sessionID": 0,
                      "sessionDetailID": 0,
                      "url": ""
                  ],
                  [
                      "firstName": atd1FirstName,
                      "lastName": atd1LastName,
                      "email": atd1Email,
                      "telNo": atd1Phone,
                      "nationality": atd1Nationatility,
                      "licenseNumber": atd1LicenseNumber,
                      "companyName": atd1CompanyName,
                      "sessionID": 0,
                      "sessionDetailID": 0,
