Alamofire API(Digest Access Authentication) data access error - ios

Question

I tried Alamofire to communicate with my server API to get the JSON data.
My API uses Digest Access Authentication, but I had problems in facing the server Challenges initially and managed to overcome with below code.
let userNameValue = "username"
let passwordValue = "password"
let credential = URLCredential(user: userNameValue, password: passwordValue, persistence: .forSession)
let sessionMananager = Alamofire.SessionManager.default
let request = sessionMananager.request("http://httpbin.org/basic-auth/\(userNameValue)/\(passwordValue)")
.authenticate(usingCredential: credential)
.responseJSON { response in
print("Response: \(String(describing: response.response))") // http url response
print("Result: \(response.result)") // response serialization result
}
The Output looked like
Response:
{ Status Code: 500, Headers {
Connection = (
close
);
"Content-Length" = (
0
);
"Content-Type" = (
"text/html; charset=UTF-8"
);
} }
Result: FAILURE
After some search I changed .responseJSON to .responseString and the output changed as below
Response:
{ Status Code: 500, Headers {
Connection = (
close
);
"Content-Length" = (
0
);
"Content-Type" = (
"text/html; charset=UTF-8"
);
} }
Result: SUCCESS
To make sure the challenge is handled I gave a wrong password and tried with .responseString, it gave the output with Status Code: 401.
Suggestions Needed
To get the data from API,
Even if Status Code: 500 is an internal error, I don't think it is the problem of server.

Answer 1

I did so like this:
let sessionMananager = Alamofire.SessionManager.default
let credential = URLCredential(user: "bruce", password: "dickinson", persistence: .forSession)
sessionMananager.request("https://httpbin.org/digest-auth/undefined/bruce/dickinson")
.authenticate(usingCredential: credential)
.responseJSON { response in
print("Result: \(String(describing: response.response?.statusCode))")
print(response.result)
print(response.description)
}
