here json app code:

your current code webpage, create server side script generate , return valid json particular url or create .json file.

for example:

create blank file called example.json , put following in it

 { "items": [{     "title": "allegiant stills released",     "date": "friday 29th january, 2016",     "content": "some more allegiant stills have been released - if can't enough! 2 have obtained of shailene's character, tris, have been added allegiant gallery in photos." }, {     "title": "allegiant stills released",     "date": "friday 29th january, 2016",     "content": "some more allegiant stills have been released - if can't enough! 2 have obtained of shailene's character, tris, have been added allegiant gallery in photos." }, {     "title": "allegiant stills released",     "date": "friday 29th january, 2016",     "content": "some more allegiant stills have been released - if can't enough! 2 have obtained of shailene's character, tris, have been added allegiant gallery in photos." }, {     "title": "allegiant stills released",     "date": "friday 29th january, 2016",     "content": "some more allegiant stills have been released - if can't enough! 2 have obtained of shailene's character, tris, have been added allegiant gallery in photos." }] 

}

then upload server , in ios application use following url:

http://annabellesykes.byethost11.com/example.json

it worthwhile reading on generating json 'on demand' though, try http://www.tutorialspoint.com/json/json_php_example.htm. it's not best tutorial out there should give starting point , show looking for.

edit:

this code working me locally..

override func viewdidload() {         super.viewdidload()         // additional setup after loading view, typically nib.          let request = nsurlrequest(url: nsurl(string: "http://local.test-application/example.json")!)         let urlsession = nsurlsession.sharedsession()         let task = urlsession.datataskwithrequest(request, completionhandler: {             (data, response, error) -> void in              if let error = error {                 print(error)                 return             }              if let data = data {                  {                      let jsonresult = try nsjsonserialization.jsonobjectwithdata(data, options: nsjsonreadingoptions.allowfragments) as? nsdictionary                      print(jsonresult)                      let jsonitems = jsonresult?["items"] as!

with json file: https://filetea.me/t1s5uhgtdlcrnudtgqimt5mqw

also if using non https url's in project you'll need allowarbitaryloads... see http://iosdevtips.co/post/121756573323/ios-9-xcode-7-http-connect-server-error
