ios - Nested JSON data will cause crash using NS Dictionary (in Swift) -

i'm trying fetch film info in json format using jsonserialization in swift , save nsdictionary. however, calling rotten tomatoes api (in info nested) cause playground crash (without giving me useful errors).

i know code valid, since calling other apis don't nest info works (but don't fulfill need).

here's code:

func getjson(urltorequest: string) -> nsdictionary { var url = nsurl(string: urltorequest) var error: nserror? allow jsondata: nsdata = nsdata.datawithcontentsofurl(url , options: nsdatareadingoptions.datareadingmapped, error: nil) allow jsondict = nsjsonserialization.jsonobjectwithdata(jsondata, options: nsjsonreadingoptions.mutablecontainers, error: &error) nsdictionary homecoming jsondict } allow moviedata: nsdictionary = getjson(apiurl)

here's sample rotten tomatoes api json (shortened illustration purposes, actual json file, not output code)

{ "id": 770672122, "title": "toy story 3", "year": 2010, "genres": ["animation", "kids & family", "science fiction & fantasy", "comedy"], "release_dates": { "theater": "2010-06-18", "dvd": "2010-11-02" }, "ratings": { "critics_rating": "certified fresh", "critics_score": 99, "audience_rating": "upright", "audience_score": 89 } }

this code works me in swift ios app (crashes xcode when run in playground:

func getjson(urltorequest: string) -> nsdictionary { var url = nsurl(string: urltorequest) var error: nserror? allow jsondata: nsdata = nsdata.datawithcontentsofurl(url , options: nsdatareadingoptions.datareadingmapped, error: nil) allow jsondict = nsjsonserialization.jsonobjectwithdata(jsondata, options: nsjsonreadingoptions.mutablecontainers, error: &error) nsdictionary homecoming jsondict } allow apiurl = "http://api.rottentomatoes.com/api/public/v1.0/movies/770672122.json?apikey=9p4xwzpgt8xp2vahnyx2sc6g" allow moviedata: nsdictionary = getjson(apiurl) println(moviedata)

it looks crash getting playground error.

note, swift guaranteed have bugs, beta.

also explicitly state json illustration code, not fro running code.
