在重新访问一些似乎可以与Xcode7.3一起工作的代码时，我注意到我得到了一个无法将"Swift._NativeDictionaryStorageOwner“（0x 40 c2134）类型的值强制转换为”NSArray“（0x 383 bb8 d8）的问题。
userdata.data 用户其他信息[索引路径.行]转换为！NSArray
以下是可能出现问题的代码部分：

func collectionView(collectionView: UICollectionView,        didSelectItemAtIndexPath indexPath: NSIndexPath) {

    let userdata:SubContentsViewController! = SubContentsViewController()
    let storyboard = UIStoryboard(name: "SubContentsViewController", bundle: nil)
    let subContentsVC = storyboard.instantiateViewControllerWithIdentifier("SubContentsViewController") as! SubContentsViewController
    userdata.data = userOtherInfo[indexPath.row] as! NSArray
    self.navigationController?.pushViewController(subContentsVC, animated: true)
}
