Need to set logo in left side of Navigation bar in AppDelegate

I am working on a swift project.In that i need the logo to be shown in left side of navigation bar and would like to make it globally in AppDelegate. But self.navigationitem is not detected in Appdelegate?Any Help would be appreciated as its my first project in swift.

     UINavigationBar.appearance().barTintColor = Constants.templatecolor
    let logoImage = UIImage.init(named: "logoImage")
    let logoImageView = UIImageView.init(image: logoImage)
    logoImageView.frame = CGRect(x: -40, y: 0, width: 150, height: 25)
    logoImageView.contentMode = .scaleAspectFit
    let imageItem = UIBarButtonItem.init(customView: logoImageView)
    let negativeSpacer = UIBarButtonItem.init(barButtonSystemItem: .fixedSpace, target: nil, action: nil)
    negativeSpacer.width = -25
    UINavigationItem.setLeftBarButtonItems(negativeSpacer, imageItem)

You can't set the Navigation item in AppDelegate. Navigation item is the property of UIViewController or UINavigationController and you set the UINavigationItem for each ViewControllers.

If all that you wanna achieve is setting the navigation title for all screens declare a base class call it as BaseViewController n in viewDidLoad of BaseViewController set the navigation item

class BaseViewController: UIViewController {

    override func viewDidLoad() {
        super.viewDidLoad()
        let logoImage = UIImage.init(named: "close")
        let logoImageView = UIImageView.init(image: logoImage)
        logoImageView.frame = CGRect(x: -40, y: 0, width: 150, height: 25)
        logoImageView.contentMode = .scaleAspectFit
        let imageItem = UIBarButtonItem.init(customView: logoImageView)
        let negativeSpacer = UIBarButtonItem.init(barButtonSystemItem: .fixedSpace, target: nil, action: nil)
        negativeSpacer.width = -25
        self.navigationItem.leftBarButtonItems = [negativeSpacer,imageItem]
        // Do any additional setup after loading the view.
    }
}

Now every single viewController in your project can extend from BaseViewController 

class ViewController: BaseViewController {
  ...
   override func viewDidLoad() {
        super.viewDidLoad()
   }
}

Make sure you call super.viewDidLoad in viewDidLoad Hope it helps

Please change x position of logoImageView while setting its frame. You are sets it's value as -40 might be because of that you are not able to see that logoImage. Change it's x position to 0.
