XIV 6 Beta 5中的UIView.animateWithDuration更改

Question

I am trying to animate a change in dimension for a UITableView. The following code worked in beta 4:

     UIView.animateWithDuration(0.1, animations: {
                tableView.frame = CGRectMake(tableView.frame.origin.x, 0 - self.calcTopOffsetToCell(indexPath), tableView.frame.size.width, tableView.frame.size.height + 190)
            }, completion: { (finished: Bool) in
                self.selectedIndex = indexPath
                cell.amountTextfield.becomeFirstResponder()
            })

In beta 5, I get the error "Missing argument for parameter 'delay' in call"

If I change the function to specify the delay:

UIView.animateWithDuration(0.5, delay: Double(0), options: .CurveLinear, animations: {
            tableView.frame = CGRectMake(tableView.frame.origin.x, 0 - self.calcTopOffsetToCell(indexPath), tableView.frame.size.width, tableView.frame.size.height + 190)
            }, completion: {
                (finished: Bool) in
                self.selectedIndex = indexPath
                cell.amountTextfield.becomeFirstResponder()
        });

I get the error "Extra argument 'delay' in call"

Not sure if I'm doing something wrong or this is a bug. Any ideas?

Even if I used the most basic syntax:

UIView.animateWithDuration(0.5, animations: {
            tableView.frame = CGRectMake(tableView.frame.origin.x, 0 - self.calcTopOffsetToCell(indexPath), tableView.frame.size.width, tableView.frame.size.height + 190)

        })

I get the "Missing argument for parameter 'delay' in call" error

似乎错误实际上与calcTopOffsetToCell（）没有返回CGFloat并且IDE错误不正确。
