Try this:
#IBAction func buton(_ sender: Any){
let params = ["acceptPrivacyNotice": true, "name" :"xxxxx xxxxx", "email": "xxxxx#mail.com", "password":"Qwerty2012", "passwordConfirm":"Qwerty2012","deviceID" : "", "isProvider" : false, "idTypeProvider": 1] as [String : Any]
let session = Foundation.URLSession.shared
let url = URL(string: "https://www.apps-sellcom-dev.com/Engie/api/account/register")
var request = URLRequest(url : url!)
request.httpMethod = "POST"
do {
let jsonData = try JSONSerialization.data(withJSONObject: params, options: .prettyPrinted)
request.addValue("M1o2K1RVMzRHVSNteUtLOjNzSCR5LUEyKk5qOEhFRg==", forHTTPHeaderField: "Authorization")
request.setValue("application/json; charset=utf-8", forHTTPHeaderField: "Content-Type")
request.httpBody = jsonData
session.dataTask(with: request, completionHandler: { data, response, error in
OperationQueue.main.addOperation {
guard error == nil && data != nil else {
print("error=\(String(describing: error))")
return
}
if let httpStatus = response as? HTTPURLResponse, httpStatus.statusCode != 200 { // check for http errors
print("statusCode should be 200, but is \(httpStatus.statusCode)")
print("response = \(String(describing: response))")
}
let responseString = String(data: data!, encoding: String.Encoding.utf8)
print("responseString = \(responseString!)")
if let responsedata = responseString!.data(using: String.Encoding.utf8)! as? Data{
do {
let jsonResult:NSDictionary = try JSONSerialization.jsonObject(with: responsedata, options: []) as! NSDictionary
print("Get The Result \(jsonResult)")
if error != nil {
print("error=\(String(describing: error))")
}
if let str = jsonResult["success"] as? NSNull {
print("error=\(str)")
}
else {
let responseString = NSString(data: data!, encoding: String.Encoding.utf8.rawValue)
print("Response string : \(String(describing: responseString))")
}
} catch let error as NSError {
print(error.localizedDescription)
}
}
}
}) .resume()
}catch {
}
}

I've tested your code and the reason you are not seeing a response is that the completion block doesn't do anything in case of failure.
When I ran your request, it came back with the following error
Error Domain=NSPOSIXErrorDomain Code=100 "Protocol error" UserInfo={NSErrorPeerAddressKey=<CFData 0x608000092200 [0x101840c70]>{length = 16, capacity = 16, bytes = 0x100201bb34bface50000000000000000}, _kCFStreamErrorCodeKey=100, _kCFStreamErrorDomainKey=1}
My best guess is that there is something wrong in the httpBody. Hope that helps.
