Terminating app due to uncaught exception 'NSUnknownKeyException'

I'm getting a strange error when I start my iOS Simulator for my app in XCode. It just stays stuck at the launch screen and I get an error at the bottom that looks like this:

What do I do about this? Here's my code in ViewController:

import UIKit

class ViewController: UIViewController {



    @IBAction func addVote() {
    }

    class ViewController: UIViewController {

     override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
        var testObject = PFObject(className:"TestObject")
        testObject["foo"] = "bar"
        testObject.saveInBackgroundWithTarget(nil, selector: nil)

        var voteCount = PFObject(className:"CountOption1")
        voteCount["votes"] = 0
        voteCount["optionName"] = "Crepes"
        voteCount.incrementKey("votes")
        voteCount.saveEventually()

        var query = PFQuery(className:"CountOption1")
        query.getObjectInBackgroundWithId("o74RWVsbHs") {
            (voteCount: PFObject!, error: NSError!) -> Void in
            if error != nil {
                NSLog("%@", error)
            } else {
                voteCount["votes"] = 0
                voteCount.incrementKey("votes")
                voteCount.saveInBackgroundWithTarget(nil, selector: nil)
            }
        }
    }

    }
    class Counter {
        var voteCount: Int = 1
        func incrementBy(amount: Int) { voteCount += amount
            println(" \(voteCount) votes")
            }

    }

       override func didReceiveMemoryWarning() {
        didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }

}
