Expected Expression Error Xcode
<p>I am running into one error when building my project and I can't seem to find a fix anywhere. The error is showing up on this line: <code>;:CGFloat = info[UIKeyboardAnimationDurationUserInfoKey] as! CGFloat</code>. Here is my code:</p>

<pre><code>func keyBoardWillShow(notification: NSNotification) {
    let info:NSDictionary = notification.userInfo!
    let keyboardSize = (info[UIKeyboardFrameBeginUserInfoKey] as! NSValue).CGRectValue()

    let keyboardHeight:CGFloat =  keyboardSize.height - 40

    // Error is on this line
    _;:CGFloat = info[UIKeyboardAnimationDurationUserInfoKey] as! CGFloat

    let contentInsets: UIEdgeInsets = UIEdgeInsetsMake(0.0, 0.0, keyboardHeight, 0.0);
    self.tableView.contentInset = contentInsets
    self.tableView.scrollIndicatorInsets = contentInsets
}
</code></pre>
