change UIViewController with your destination view controller.
for e.g your destinationviewcontroller name is YourViewControllerand also use if let for safely unwrap
使用目标视图控制器更改 UIViewController。例如，您的目的地YourViewController视图控制器名称是并且还使用 if let 安全解包
override func prepareForSegue(segue: UIStoryboardSegue, sender: AnyObject?) {
if let DestVC = segue.destinationViewController as? YouViewController {
var indexPath : NSIndexPath = self.tableView.indexPathForSelectedRow!
DestVC.varView = indexPath.row
}

replace
代替
var DestVC = segue.destinationViewController as UIViewController
with
和
var DestVC = segue.destinationViewController as YourDestinationClassName
and make sure that there is a varViewmember available in that class
并确保varView该类中有可用的成员
