Error in Code

[cesarmtz93]

Hi I´ve set up the project of a uitabcontroller and the drawer as the issue #41, but i have a view controller with a button action performing the next code

    let drawer = self.navigationController!.parent?.parent as! KYDrawerController
    drawer.setDrawerState(.opened, animated: true)

im getting this error "Could not cast value of type 'KYDrawerController.KYDrawerController' (0x1012c3b00) to 'renti.KYDrawerController' (0x100cb5db0)."

As indicated by the error statement, self.navigationController!.parent?.parent is not a KYDrawerController type.
Please understand viewcontroller hierarchy.

I don't think it's about the hierarchy, because i had it this way since swift 2.2 and now that it was updated and you said in the ticket #57, that we need to set module column, now it breaks

because if I print this line self.navigationController!.parent?.parent i get Optional(KYDrawerController.KYDrawerController: 0x7fc0add0b270)

so it's module.class and the error Could not cast value of type 'KYDrawerController.KYDrawerController' to 'renti.KYDrawerController' , so it´s a casting problem between that.

It will work without problems in this sample code.
Please check the implementation or configuration！

viewController hierarchy is wrong!!

@IBAction func buttonDidTap(_ sender: UIButton) {
        let drawer = tabBarController?.parent as! KYDrawerController
        drawer.setDrawerState(.opened, animated: true)
 }

Here is not the place to ask questions. It is the place to report the issue!!
First of all, please check the cause of the problem on their own.
