Alamofire request is send twice - swift

Question

I’m alamofire request, and I found the request is sent twice. Is it an alamofire bug?
I tried to put a breakpoint, but it's not called twice and there is no button call this function twice or trigging twice.
Here is my code
ARSLineProgress.show()
guard let url = URL(string: "https://laghmat.kbmediawebites.com/api/rest/account") else {return}
let headers = ["X-Oc-Merchant-Id": MerchantId, "X-Oc-Session": K_Defaults.string(forKey: "sessionID"),"ACCEPT":"application/json"]
let params = [
"firstname": firstName,
"lastname": lastName,
"email": email,
"telephone": phone
] as! [String : String]
Alamofire.request(url, method: .put, parameters: params,encoding: JSONEncoding.default, headers: headers as! HTTPHeaders).responseJSON {
response in
switch response.result {
case .success:
print(response)
guard let data = response.data else { return }
do {
let value = try JSONDecoder().decode(GeneralResponse.self, from: data)
if value.success == 1 {
ARSLineProgress.showSuccess()
var user = GlobalHelpers.getUser()
user?.firstname = firstName
user?.lastname = lastName
user?.telephone = phone
user?.email = email
GlobalHelpers.setUser(user)
self.dismiss(animated: true, completion: nil)
} else {
ARSLineProgress.showFail()
self.alert(msg: LanguageManger.localize(word: "serverError"))
}
} catch let error {
ARSLineProgress.showFail()
self.alert(msg: LanguageManger.localize(word: "serverError"))
print(error)
}
break
case .failure(let error):
ARSLineProgress.showFail()
self.alert(msg: LanguageManger.localize(word: "serverError"))
print(error)
}
}

well I recommend you that lock all the buttons in the view, when the request is made.
for viewW in view.subviews
{
if let buttonV = viewW as? UIButton
{
buttonV.isUserInteractionEnabled = false
}
}
obviously, you have to lock at the beginning and unlock at the end.
if this isn't works, put a breakpoint in this line
switch response.result {
the first time, you will see that you don't have a status code, because the server not yet responding, then press next step, and you will see a status code, because the server already responds to you.
that doesn't mean the request is made twice, I think that this happen because the handshake is happening.
