How to animate the swift menu slide

Made a custom menu slide. Now the problem with the animation is closing the menu. In theory, he should go from left to right and go back. And not all elements then leave the screen, how to remove them with the view ? Here's a video

Here is the code

 import UIKit public extension UIDevice { var modelName: String { var systemInfo = utsname() uname(&systemInfo) let machineMirror = Mirror(reflecting: systemInfo.machine) let identifier = machineMirror.children.reduce("") { identifier, element in guard let value = element.value as? Int8 where value != 0 else { return identifier } return identifier + String(UnicodeScalar(UInt8(value))) } switch identifier { case "iPhone4,1": return "iPhone 4s" case "iPhone5,1", "iPhone5,2": return "iPhone 5" case "iPhone5,3", "iPhone5,4": return "iPhone 5c" case "iPhone6,1", "iPhone6,2": return "iPhone 5s" case "iPhone7,2": return "iPhone 6" case "iPhone7,1": return "iPhone 6 Plus" case
