Answer 1

I created new var for my controller and i added new subview in this

let controller = self.dataSource.storyboard!.instantiateViewController(withIdentifier: 
self.destitaionController as String)
self.dataSource.addChild(controller)
controller.didMove(toParent: self.dataSource)
controller.view.frame = CGRect(x: 0, y: 0, width: (cardSelected?.frame.width)!, height: (cardSelected?.frame.height)!)
controller.view.alpha = 0.0
self.dataSource.view.addSubview(controller.view)
controller.view.alpha = 1.0
