Hope that helps I am building an app in iOS using SWIFT and i have also been using swiftyJSON to make this project a little easier.
code :
let users = readableJSON["users"]
let user = users[0] // get info of the first user, you should check more here
let email = user["email"]
if let users = readableJSON["users"], user = users.first, email = user["email"]

seems to work fine You need to use fetch statement to get data after query execute function
code :
$query->execute();
$data = $query->fetchAll();
echo json_encode($data);
foreach($query as $row) {
         echo json_encode($row); 
    }
$result = []
foreach($query->fetch() as $row) {
    $result[] = $row;
}
echo json_encode($result);

like below fixes the issue You can only send one json output and you are sending several.
Try sending:
code :
<cfoutput>#SerializeJSON(session.dealerwork)#</cfoutput>

this one helps. Your server is returning invalid data. Fine uploader expects a valid JSON response, and, as you can see in the error message, that is not happening. You'll need to take a close look at your server code.

hope this fix your issue it's not a valid json, you must wrap it in array. the valid json is like this
code :
[{
    "results": [{
        "oldID": 5,
        "oldMain": "News papers"
    }]
}, {
    "results": [{
        "oldID": 3,
        "oldMain": "Construction"
    }]
}, {
    "results": [{
        "oldID": 2,
        "oldMain": "Banking Files"
    }]
}, {
    "results": [{
        "oldID": 1,
        "oldMain": "Technologies"
    }]
}]

it should still fix some issue jQuery parses the JSON for you before calling success because you've specified dataType: 'json'. (If you hadn't, and the server replied with the correct Content-Type, it would have done it anyway.) So you can just use data directly, you don't want to call JSON.parse on it.
So change your success function from
