my ios-swift code receives nsdictionary object after beingness parsed afnetworking lib , passes function casts results array nsdictionary[], throwing run-time error, while before working.

(operation: afhttprequestoperation!, responseobject: anyobject!) in println("json: " + responseobject.description) var jsonresult: nsdictionary = responseobject nsdictionary

this jsonresult passed function below tries cast nsdictionary[]

let allresults: nsdictionary[] = results["results"] nsdictionary[]

update: printed class of results object beingness returned __nscfdictionary.

here what nscfdictionary? give-and-take regarding , says utilize nsdictionary, in case not working.

the value of results not dictionary in json, array. should this;

let allresults: nsarray = results["results"] nsarray

ios json swift
