swift - Alamofire 3.3 JSON ObjectMapping -

i'm using alamofire 3.3 in swift 2

edited question after more research..

i think mapping wrong, have no idea how should change it. can see snippets use key->value elements try map dont have tell mapping go 1 level lower? , if how should go it?
keys changing, how can map such things?

[old question]
strange markup response rest service json code correct use elsewhere, join snippet of how service sends , how function receives use object mapper, posted under func

removed if around mapping part , got error:

fatal error: unexpectedly found nil while unwrapping optional value

func getpanden(url:nsurl, success:(value:[pand])->(), failed:(value:nserror)->()) {      alamofire.request(.get, "\(base_url)\(url)").responsejson {          response in         if let json = response.result.value {             print(response)             if json.count >= 1 {                 // print(json);                 if let panden:array<pand> = mapper<pand>().maparray(json) { //use var transform else let                     success(value: panden)                 }             } else {                 failed(value:nserror(                     domain: "ehb.pulseapp.watchkitapp.watchkitextension"                     ,code: -10                     ,userinfo: [nslocalizedfailurereasonerrorkey: "error.data.status.not.found"]))             }         }      }  } 

the mapping:

func mapping(map: map) {     pand_id    <- map["pand_id"]     name    <- map["name"]     street    <- map["street"]     city    <- map["city"]     zip    <- map["zip"]     country    <- map["country"]     geolocation_lat    <- map["geolocation_lat"]     geolocation_long    <- map["geolocation_long"]     image    <- map["image"] } 

how json looks in browser:

{     "pand_2": {         "pand_id": "21",         "name": "ludovic marchand",         "street": "victor mertensstraat 13",         "city": "hoeilaart",         "zip": "1560",         "country": "belgium",         "geolocation_lat": "2",         "geolocation_long": "3",         "image": "1460980598349.png"     },     "pand_3": {         "pand_id": "22",         "name": "chez chloé",         "street": "groenstraat 36",         "city": "zaventem",         "zip": "1930", <-------see how there quotes around elements         "country": "belgium",         "geolocation_lat": "50.8869256",         "geolocation_long": "4.4652817",         "image": "1460980775092.jpg"     }, <--- how should     ... } 

and here how looks when alamorfire receives it:

{     "pand_2" =     {         city = hoeilaart;         country = belgium;         "geolocation_lat" = 2;         "geolocation_long" = 3;         image = "1460980598349.png";         name = "ludovic marchand";         "pand_id" = 21;         street = "victor mertensstraat 13";         zip = 1560;     };     "pand_3" =     {         city = zaventem;         country = belgium;         "geolocation_lat" = "50.8869256";         "geolocation_long" = "4.4652817";         image = "1460980775092.jpg";         name = "chez chlo\u00e9";         "pand_id" = 22;         street = "groenstraat 36";         zip = 1930; <---- zip should "zip"     }; <---- should ,     ... }
