so please correct me going wrong .

thanks in advance

your code has number of issues.

in order create url query params, recommend use utility class nsurlcomponents (see apple documentation: nsurlcomponents).

composing post request content type "multipart/formdata" quite error prone. if absolutely have compose such request strongly recommend use network library, example afnetworking.

on other hand, using post request content-type application/json easy setup, nsurlsession , friends.

you can find specific solutions of suggested approaches mentioned above on so, too.
