JSON Question

Serializing data into JSON using older swift method 'JSONObjectWithData?

I'm sorry if this may seem that I haven't read or updated my information on Swift 2.2 but I actually already have and I've gone through the updated method but still am receiving errors(I didn't state them here because thats not my issue; my issue is writing the JSONObjectWithData in its updated syntax form)

I took this function from an older swift book and am trying to get it to Parse the data into JSON. I used the updated syntax for the method JSONObjectWithData() but wasn't able to piece the syntax pieces together. My problem isn't the compiler screaming at me with errors because I know that I was rewriting the JSONObjectWithData method wrong, heres the old syntax that I tried to rewrite but couldn't do so successfully.

I still haven't wrapped my head around the concept of parsing data into JSON even after studying the chapter and reading the Apple documentation, let alone try to rewrite the JSONObjectWithData method correctly. I searched a similar answer to this and could not figure out how to write this book method correctly in the updated syntax and have it run without errors. I've been stuck on this for 2 days.

func parseJson(data: NSData) {
var error: NSError?
let json: AnyObject? = NSJSONSerialization.JSONObjectWithData(data, options: .allZeros, error: &error)
if error == nil {
if let unwrappedJson: AnyObject = json {
parseSongs(json: unwrappedJson)


Have you tried this block of code:

let json: AnyObject? = try! NSJSONSerialization.JSONObjectWithData(data, options: .AllowFragments)
