Here is the Example of POST API for calling Login API with parameters "emailaddress" and "password" with userEmailID and Userpassword as two strings holding values for email and password respectively.

You can call this POST API anywhere in your view controller, as given below:

self.postLoginCall(url: "Your post method url") example: self.postLoginCall(url: "http://1.0.0.1/api/login.php")

func postLoginCall(url : String){


    let request = NSMutableURLRequest(url: NSURL(string: url)! as URL)
    request.httpMethod = "POST"
    let postString = "emailaddress=\(userEmailID!)&password=\(Userpassword!)"
    print(postString)
    request.setValue("application/x-www-form-urlencoded; charset=utf-8", forHTTPHeaderField: "Content-Type")
    request.httpBody = postString.data(using: String.Encoding.utf8)

    let task = URLSession.shared.dataTask(with: request as URLRequest) { data, response, error in
        guard error == nil && data != nil else {                                                          // check for fundamental networking error
            print("error=\(error)")
            return
        }

        do {
        if let responseJSON = try JSONSerialization.jsonObject(with: data!) as? [String:AnyObject]{
            print(responseJSON)
            print(responseJSON["status"]!)


            self.response1 = responseJSON["status"]! as! Int

            print(self.response1)

            //Check response from the sever
            if self.response1 == 200
            {
                OperationQueue.main.addOperation {

                    //API call Successful and can perform other operatios
                   print("Login Successful")
                }

            }

            else
            {
                OperationQueue.main.addOperation {

                    //API call failed and perform other operations
                    print("Login Failed")

                }

            }


        }
        }
        catch {
            print("Error -> \(error)")
        }



    }


    task.resume()



}
