import SideMenu

class ProfileViewController: UIViewController, UITextFieldDelegate {

  override func viewDidLoad() {
      super.viewDidLoad()
  }
 @IBAction func sideMenubtn(_ sender: Any) {
   view?.backgroundColor = UIColor(white: 1, alpha: 0.9)
}
}


extension ProfileViewController : SideMenuNavigationControllerDelegate 
{
func sideMenuWillDisappear(menu: SideMenuNavigationController, animated: Bool) {
  view?.backgroundColor = UIColor.white
}

import SideMenu
import UIKit

class ViewController: UIViewController {

    var menu: SideMenuNavigationController?

    override func viewDidLoad() {
        super.viewDidLoad()
        // Do any additional setup after loading the view.
        menu = SideMenuNavigationController(rootViewController: MenuListController())
        menu?.leftSide = true
        menu?.setNavigationBarHidden(true, animated: false)
        SideMenuManager.default.addPanGestureToPresent(toView: self.view)
        SideMenuManager.default.leftMenuNavigationController = menu
    }

    @IBAction func didTappedMenu() {
        present(menu!, animated: true)

    }
}

class MenuListController: UITableViewController {

    var item = ["one","two","there","four","five","six","seven","eight","nine"]
    let darkColor = UIColor(red: 33/255.0, green: 33/255.0, blue: 33/255.0, alpha: 1)

    override func viewDidLoad() {
        super.viewDidLoad()
        tableView.register(UITableViewCell.self, forCellReuseIdentifier: "cell")
        tableView.backgroundColor = darkColor

    }

    override func tableView(_ tableView: UITableView, numberOfRowsInSection section: Int) -> Int {
        return item.count
    }

    override func tableView(_ tableView: UITableView, cellForRowAt indexPath: IndexPath) -> UITableViewCell {
        let cell = tableView.dequeueReusableCell(withIdentifier: "cell" , for: indexPath)
        cell.textLabel?.text = item[indexPath.row]
        cell.textLabel?.textColor = .white
        cell.backgroundColor = darkColor
        return cell
    }

    override func tableView(_ tableView: UITableView, didSelectRowAt indexPath: IndexPath) {
        tableView.deselectRow(at: indexPath, animated: true)
    }
}

When possible, please make an effort to provide additional explanation instead of just code. Such answers tend to be more useful as they help members of the community and especially new developer better understand the reasoning of the solution, and can help prevent the need to address follow-up questions. — Rajan, May 07 '20 at 06:28

You can implement SideMenuNavigationControllerDelegate methods in your view controller and then change color when sideMenuWillDisappear triggers

Add delegate methods. it will work you can see the following code-

extension YourClassName : SideMenuNavigationControllerDelegate {
func sideMenuWillDisappear(menu: SideMenuNavigationController, animated: Bool) {
    *do the color thing*
}
}

And keep in mind to do-

import SideMenu

But i will not recommend you to change the color of view like this. You can use alpha property of side menu to dark the background view while presenting the side menu. Take reference from -

let menu = storyboard!.instantiateViewController(withIdentifier: "SideMenuNavigationController") as! SideMenuNavigationController
    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.sideMenuManager.addScreenEdgePanGesturesToPresent(toView: self.view)
    menu.settings = set
    //SideMenuManager.default.addScreenEdgePanGesturesToPresent(toView: view)
    SideMenuManager.default.leftMenuNavigationController = menu

You dont need to add delegate in view didload. you can place the second code in a function and call the function in the veiwdidload(of the masterview on which the side menu will appear.) – Piyush Sharma Dec 26 '19 at 11:47
