In my code, I have defined a class called `BannerResponse` that looks like this:
class BannerResponse : NSObject{
let URL = "Url";
let CONTACT_NO = "ContactNo";
let IMAGE = "Image";
let BIG_IMAGE = "BigImage";
let ID = "Id";
let TITLE = "Title";
let NO_VIEW = "NoView";
let START_DATE = "StartDate";
let END_DATE = "EndDate";
var url:String;
var contactNo:String;
var image:String;
var bigImage:String;
var title:String;
var id:Int;
var noView:Int;
var startDate:String;
var endDate:String;
init(data : NSDictionary){
url = data[URL] as! String;
contactNo = data[CONTACT_NO] as! String;
image = data[IMAGE] as! String;
bigImage = data[BIG_IMAGE] as! String;
title = data[TITLE] as! String;
id = data[ID] as! Int;
noView = data[NO_VIEW] as! Int;
startDate = data[START_DATE] as! String;
endDate = data[END_DATE] as! String;
}
}
When the code is executed, an error occurs with the following message:
Could not cast value of type 'NSNull' (0x10a85f378) to 'NSString' (0x109eccb20).
EDIT
do {
if let json = try NSJSONSerialization.JSONObjectWithData(data!, options: NSJSONReadingOptions.MutableContainers) as? NSDictionary{
onSuccess(BannerResponse(data: json))
}
} catch {
onFail()
}
