[SWIFT4] How to handle Error

My code looks like this:

  AuthAPI.login(loginRequest: request) { (response : LoginResponse?, error :  Error?) in
            if error != nil {
                
            }
            
            if response != nil {
                if response!.result.success {
                    self.loginSuccess(data: response!.result.data!)
                }
            }
        }

How can i get the http status code from error if there is one ?

Start with the generated Swift 4 AuthAPI.login entry point shown in the issue and inspect the callback's Error type and response handling. No generated file or test is named; done would be a documented, verified way to access the HTTP status code, or a clear statement that the client does not expose it.
