Presenting view controllers on detached view controllers is discouraged

[kamirana4]

I have UINavigationController as initial view controller which contains LoginViewController. After login, i am adding the SlideMenuController from the LoginViewController and after present completion i am setting the SlideMenuController as the rootviewcontroller. Code below,

self.navigationController?.present(slideMenuController, animated: true, completion: {
            appDelegate.window?.rootViewController = slideMenuController
        })

The issue i am facing is if i add UIAlertController in the mainViewController of SlideMenuController, it gives this error,

Presenting view controllers on detached view controllers is discouraged <SlideMenuControllerSwift.ExSlideMenuController: 0x100c160c0>.

I also tried the following to check if it fixes the issue but got the same issue,

self.present(slideMenuController, animated: true, completion: {
            appDelegate.window?.rootViewController = slideMenuController
        })

The workaround i found is, if i set the SlideMenuController as rootviewcontroller without animating like below,

appDelegate.window?.rootViewController = slideMenuController

But i want the animation effect and i also don't want to use the view's -CAAnimation for now. I want a better fix for this.

I changed the SlideMenu example project by adding one extra ViewController to produce the issue. Example project can be downloaded from the following path.

The issue was about wrong presentation of the slide menu controller.
