parse json using swift2 and error with NSJSONReadingOptions

Question

I am trying to parse an json from a webserver i am using and i can't actually manage to do that although i could back in iOS 8. This is the code i am using:

let str = "URL-THAT-HAS-THE-JSON"

let url = NSURL(string: str)

let data = NSData(contentsOfURL: url!)

var names : [String] = []
do
{
    let json = try NSJSONSerialization.JSONObjectWithData(data!, options: [] )
    if let blogs = json["blogs"] as? [[String: AnyObject]]
    {
        for blog in blogs
        {
            if let name = blog["name"] as? String
            {
                names.append(name)
            }
        }
    }
}
catch {
    print("error serializing JSON: \(error)")
}
print (names)

unfortunately i can't give you the url with the json but i can make sure it works on server side.Could someone give me some help on what i am doing wrong?

`options: nil` should be `options: []`, as (e.g.) in http://stackoverflow.com/questions/30769387/swift-2-0-calendar-components-error and some more similar questions. — Martin R, Oct 18 '15 at 18:16
ok i just did that and switched from nil to [ ] but that doesn't seem to fix the issues cause i am still getting the EXC_BAD_INSTRUCTION error in that line. Any ideas what's wrong? — Korpel, Oct 18 '15 at 18:18
What do you mean by "still getting"? Your original code did not compile at all, therefore it cannot crash at runtime. Also you did not describe the issue in the question, apart from *"i can't actually manage"*. — Martin R, Oct 18 '15 at 18:21
yes data is nil so i am explicity unwrapping a nil value therefore my app crashes. Thanks — Korpel, Oct 18 '15 at 18:23
