How to add transparent background while open the side menu in swift?

I am using left side menu from jonkykong/SideMenu. If I open side menu I need transparent background view and if i close then background should change to its original colour. For that i am trying to set alpha value for side menu.

I have tried two ways:

1) Here i have installed pod 'SideMenu' and added below code:

 import UIKit
 import SideMenu

class ViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        sideMenuConfig()
    }
    func sideMenuConfig(){
        // Define the menus
        SideMenuManager.default.menuLeftNavigationController = storyboard!.instantiateViewController(withIdentifier: "UISideMenuNavigationController") as? UISideMenuNavigationController
        var set = SideMenuSettings()
        set.presentationStyle.presentingEndAlpha = 1
        SideMenuManager.default.menuPresentMode = .menuSlideIn
        SideMenuManager.default.menuFadeStatusBar  = false
        SideMenuManager.default.menuAddPanGestureToPresent(toView: self.navigationController!.navigationBar)
        SideMenuManager.default.menuAddScreenEdgePanGesturesToPresent(toView: self.navigationController!.view)
    }
} 

here why pod not recognising SideMenuSettings.

error: Use of unresolved identifier 'SideMenuSettings'

2) Updated pod to swift 5 pod 'SideMenu', '~> 6.0' and below code:

 import UIKit
 import SideMenu

 class ViewController: UIViewController, SideMenuNavigationControllerDelegate {

    override func viewDidLoad() {
        super.viewDidLoad()
        menuSettings()
    }
    func menuSettings(){
        let menu = storyboard!.instantiateViewController(withIdentifier: "SideMenuNavigationController") as! SideMenuNavigationController
        menu.blurEffectStyle = nil
        var set = SideMenuSettings()
        set.statusBarEndAlpha = 0
        set.presentationStyle = SideMenuPresentationStyle.menuSlideIn
        set.presentationStyle.presentingEndAlpha = 0.5
        set.menuWidth = min(view.frame.width, view.frame.height) * 0.90
        menu.settings = set
        SideMenuManager.default.leftMenuNavigationController = menu
    }
}

here background view also moving with side menu like below How add give alpha value to side menu in swift.

Please help with the side menu code.

Just create a subclass of SideMenuNavigationController and set the presentationStyle's backgroundColor and presentingEndAlpha properties in it. From now on, you can use your CustomSideMenuNavigationController as your SideMenuNavigationController.

class CustomSideMenuNavigationController: SideMenuNavigationController {

    override func viewDidLoad() {
        super.viewDidLoad()

        setNavigationBarHidden(true, animated: false)

        self.presentationStyle = .menuSlideIn
        self.presentationStyle.backgroundColor = .white
        self.presentationStyle.presentingEndAlpha = 0.7

        self.statusBarEndAlpha = 0.0
        self.menuWidth = (UIScreen.main.bounds.width / 5) * 4
    }

}
