string - Unwrapping Json Swift (found nil) -

i trying decode json in xcode, not succed 1 of them.

this :

[   {      "id": "1",      "title": "bmw",      "price": "500.00",      "description": "330",      "addeddate": "2015-05-18 00:00:00",      "user_id": "1",      "user_name": "canovas",      "user_zipcode": "32767",      "category_id": "1",      "category_label": "vehicules",      "subcategory_id": "2",      "subcategory_label": "motos",      "bdd": {}    }      "pictures":          [          { "name": "http://cars.axlegeeks.com/sites/default/files/4315/media/images/2014_bmw_z4_sdrive28i_3790993.jpg"          }         ]   } ] 

and want value of "name" "pictures" lines have error "unexpectedly found nil while unwrapping value".

for others values proceed way :

let jsondata:nsdictionary = nsjsonserialization.jsonobjectwithdata(urldata!, options:nsjsonreadingoptions.mutablecontainers , error: &error) as! nsdictionary              //browse json datas             let resp = jsondata["0"] as! nsdictionary                 let user_namer = resp["user_name"] as! string                 let user_zipcoder = resp["user_zipcode"] as! string                 let titler = resp["title"] as! string                 let pricer = resp["price"] as! string                 let descriptionr = resp["description"] as! string 

thank's !

pictures in not in subdictionary other values are. should work, should check values if nil before force cast them.

if let picturearray = jsondata["pictures"] as? nsarray {     if let picturedict = picturearray.firstobject as? nsdictionary     {         if let picturename = picturedict.objectforkey("name") as? string         {             nslog("picture name: %@", picturename)         }     } } 

jsondata contains 2 sub-dictionaries, 1 without key , 1 key 'pictures'. pictures array containing 1 sub-dictionary.
