iOS Swift: Parsing response json with AFNetworking

Question

So, I am using AFNetworking 2.0 (ObjC framework with Bridging-Header) to make some requests on a local server. I have followed a few tutorials to code it using Swift. This is the code:

var success = { (operation:AFHTTPRequestOperation!, response:AnyObject!) -> Void in
    println(response.description)
    successBlock(result:response.description)
}

var failure = { (operation:AFHTTPRequestOperation!, response:NSError!) -> Void in
    println(response.description)
    errorBlock(error:response.description)
}

var manager = AFHTTPRequestOperationManager()
manager.responseSerializer = AFJSONResponseSerializer();
manager.GET("http://127.0.0.1:8080/api/manufacturer", parameters: nil, success: success, failure: failure)

It retrieves the json and prints it successfully. The response is something like this:

(
        {
        "_id" = 539f0973e3c7f4ab1f6078f5;
        name = Manufacturer01;
    },
        {
        "_id" = 539f18c5e3c7f4ab1f6078f6;
        name = Manufacturer02;
    }
)

However, I am unable to parse it... I tried response[0] to get the first element, but it crashes the simulator and even Xcode6 when I try to do: (lldb) > po response[0]. I tried everything, every example I have seen explains how to print the result but nothing about parsing each field.

The response object looks like this when I try to debug it:

value = Some {
    Some = (instance_type = Builtin.RawPointer = 0x0b240710 -> 0x00bc5da0 (void *)0x00bc5db4: __NSCFArray)
  }

Any clue? Thanks in advance!

try this

if let responseArray = response as? NSArray {
    let firstElement = responseArray[0]
    // do something with the first element
}
