title: Swift 2: "Bool' is not convertible to 'BooleanLiteralConvertible'
body: <p>I created an app in <code>XCode 6</code>. Today I downloaded <code>XCode 7</code> and it had updated my app to <code>Swift 2</code>. There were a lot of errors, but now there is only one that I can't solve.
  I don't know why, but <code>Xcode</code> doesn't like any <code>Bool</code> option for <code>animated</code> and show this error - </p>
  
  <blockquote>
    <p>'Bool' is not convertible to 'BooleanLiteralConvertible'</p>
  </blockquote>
  
  <p>(if you look at the function itself, you will see, that it takes exactly the <code>Bool</code> for <code>animated</code>)</p>
  
  <pre><code>var startVC = self.viewControllerAtIndex(indexImage) as ContentViewController
  var viewControllers = NSArray(object: startVC)
  
  self.pageViewContorller.setViewControllers(viewControllers as [AnyObject], direction: UIPageViewControllerNavigationDirection.Forward, animated: true, completion: nil)
      'Bool' is not convertible to 'BooleanLiteralConvertible'
  </code></pre>
  
  <p>Does anybody know, how can I solve it?</p>
  
  <p>Thanks.</p>
