Swift 4.0

let customView = UIView(frame: CGRect(x: 0, y: self.view.frame.size.height-300, width: self.view.frame.size.width, height: 300))
customView.backgroundColor = UIColor.red
customView.layer.zPosition = CGFloat(MAXFLOAT)
let windowCount = UIApplication.shared.windows.count
UIApplication.shared.windows[windowCount-1].addSubview(customView)
