• how obtain values without key of dictionary? 1 answer

i trying parse json files url. json has key dynamic, in changes per file. right code looks this:

let json = try nsjsonserialization.jsonobjectwithdata(data!, options:.allowfragments)                   // parsing                 if let stations = json["observations"]!!["-10019482"] as? [[string: anyobject]] {                      observation in stations {                          if let name = observation["stationname"] as? string {                              if let temperatuuri = observation["temperature"] as? string {                                 if let windspeed = observation["windspeedms"] as? string {                                     print(name, temperatuuri, windspeed,"m/s")                                     self.temperature.text = string(temperatuuri)                                 }                             }                          }                      }                 } 

"-10019482" part changed dynamically , key name cannot predicted. however, know first key inside "observations".

how same, without searching specific key name?

since json["observations"] dictionary obtain it's first key

guard let dict = json["observations"] as? [string: anyobject],     let firstkey = dict.keys.first else { return }  print(firstkey) // should print first key found in observations dictionary
