How to change an NSData to an NSDictionary or JSON - ios

Question

I have a swift app that calls api and recieves back a JSON.
self.get(url).responseJSON { (response) -> Void in
self.notify(FetchCompletion, response: response.response, result: response.result)
print("response: ")
print(response.response)
print("data: ")
let dataExample = response.data
print(dataExample)
let dictionary:NSDictionary? = NSKeyedUnarchiver.unarchiveObjectWithData(dataExample!)! as? NSDictionary
}
And it prints out:
...
data:
Optional(<7b227374 61747573 223a2234 3034222c 22657272 6f72223a 224e6f74 20466f75 6e64227d>)
fatal error: unexpectedly found nil while unwrapping an Optional value
I want to just print out the data is some readable form by converting to a dictionary.
EDIT 1
My get() function is defined as such:
func get(path: String) -> Request {
return self.get(path, data: NSDictionary())
}
EDIT 2
I am using
import UIKit
import Alamofire
import SwiftyJSON
EDIT 3
I attempted to follow the example here:How to parse JSON in Swift using NSURLSession
But get the error "unresolved identifier 'JSONSerialization'"
EDIT 4 / probable answer
var newdata = JSON(data: dataExample!)
print(newdata)
outputted:
{
"status" : "404",
"error" : "Not Found"
}
I believe that this is a json and I am properly printing the readable data, so i believe this is the answer. I was led to this by the comment suggesting to use swiftJSON

Answer 1

A very standard way to convert to JSON from NSData, feel free to ask a question
self.get(url).responseJSON { (response) -> Void in
self.notify(FetchCompletion, response: response.response, result: response.result)
print("response: ")
print(response.response)
print("data: ")
let dataExample = response.data
print(dataExample)
do {
let dictionary = try NSJSONSerialization.JSONObjectWithData(dataExample!, options: NSJSONReadingOptions()) as! NSDictionary
}
catch {
// catch error.
}
}
