CGSizeMake不可用

Question

当我想在最新的Xcode中使用CGSizeMake时出现错误。它说CGSizeMake不再适用于Swift。如何正确修复此错误？

var V1 : View1 = View1(nibName: "View1", bundle: nil)

var V2 : View2 = View2(nibName: "View2", bundle: nil)


self.addChildViewController(V1)
self.scrollView.addSubview(V1.view)
V1.didMove(toParentViewController: self)

self.addChildViewController(V2)
self.scrollView.addSubview(V2.view)
V1.didMove(toParentViewController: self)

var V2Frame : CGRect = V2.view.frame
V2Frame.origin.x = self.view.frame.width
V2.view.frame = V2Frame

self.scrollView.contentSize = CGSizeMake(self.view.frame.width * 2, self.view.frame.size.height)
