"Expected Declaration" in Swift
<p>I tried to code a program which has two images. I use 4 buttons UP, DOWN, LEFT, RIGHT to move one image. <strong>If that image reaches the other, a text field will show up: "You are the winner!".</strong></p>

<p>However, the line containing the code If... always gets "Expected Declaration" error. How can I make it run, pls?</p>

<p>This is the whole code, the names of two images are ConChimCu and Trung:</p>

<pre><code>import UIKit

class ViewController: UIViewController {
    @IBOutlet weak var txtBai: UITextView!
    @IBOutlet weak var ConChimCu: UIImageView!
    @IBOutlet weak var Trung: UIImageView!

    @IBAction func Up(sender: AnyObject) {
       ConChimCu.frame.origin.y = ConChimCu.frame.origin.y - 2
   }

    @IBAction func RIGHT(sender: AnyObject) {
        ConChimCu.frame.origin.x = ConChimCu.frame.origin.x + 2
    }

    @IBAction func DOWN(sender: AnyObject) {
        ConChimCu.frame.origin.y = ConChimCu.frame.origin.y + 2
    }

    @IBAction func LEFT(sender: AnyObject) {
        ConChimCu.frame.origin.x = ConChimCu.frame.origin.x - 2
    }

    if ConChimCu.frame.origin.x == Trung.frame.origin.x { txtBai.text = "You are the winner!"
    }

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view, typically from a nib.
    }

    override func didReceiveMemoryWarning() {
        super.didReceiveMemoryWarning()
        // Dispose of any resources that can be recreated.
    }
</code></pre>
