POST request from Swift fails while it works in Postman

I've a django REST api which works perfectly when called over POSTMAN or an android client. However when I try to call it in Swift I get a 405.

This is my code,

import Foundation

let url = URL(string: "http://example.com/xx/x/xxx/sports")!
var request = URLRequest(url: url)
request.setValue("application/json", forHTTPHeaderField: "Content-Type")
request.httpMethod = "POST"
let postString = "client_id=xx&client_secret=yy"
request.httpBody = postString.data(using: .utf8)
let task = URLSession.shared.dataTask(with: url) { (data, response, error) in
    guard let data = data else {return}
    do{
        //try validate(response)
        //parse data
        print(response)
    }catch{
        print(error)
    }

    //print(String(describing: data))
}
task.resume()

Can someone help me with this?

405 Method Not Allowed response status code indicates that the request method is known by the server but is not supported by the target resource.

The server MUST generate an Allow header field in a 405 response containing a list of the target resource's currently supported methods.

Check the httpMethod. You may need GET or other HTTP method instead of POST

Update:

Replace let postString = "client_id=xx&client_secret=yy" with let postString = "{client_id=\"xx\", client_secret=\"yy\"}"

Also you should use URLSession.shared.dataTask(with: request) not with url. See the code below:

URLSession.shared.dataTask(with: request) { data, response, error in
  if let response = response, let data = data {
    print(response)
    print(String(data: data, encoding: .utf8))
  } else {
    print(error)
  }
}

As you're using 

let task = URLSession.shared.dataTask(with: url) { (data, response, error) in...

Your request setup code is ignored. GET method is default, and it is not allowed on your server.

If it is working on POSTMAN Then you can get that code from that itself. Copy that code and paste in Playground. It should work. Compare with your code. Fix the issues.
