PageViewController 崩溃 setViewControllers

Question

我有 PageViewController，我想显示 viewControllerAtIndex 这是我的代码：

let startingViewController: MyPages = self.viewControllerAtIndex(0, storyboard: self.storyboard!)!
let viewControllers: NSArray = [startingViewController]
pageViewController.setViewControllers(viewControllers as [AnyObject], direction: .Forward, animated: false, completion: nil)

但我的应用因 Terminating app due to uncaught exception 'NSRangeException', reason: '*** -[__NSArrayI objectAtIndex:]: index 0 beyond bounds for empty array'

而崩溃

viewControllers 在 println 上不为空我有 <My_App.MyPages: 0x7fcce9813e00> 这发生在新的 beta 3 on 8.3 on beta 2 上。
