I have searched every where to find a solution to this error i am getting, i have also tried to use, nsuserdefaults, struct and global var to pass on my vars to other viewcontrollers. I am use mmdrawer and i have set a navigationcontrol on my first viewcontroller that who i named userOview and identifier membersArea. Whenever i try to use prepareforsegue i am getting the following error

Could not cast value of type 'xxxxxxxx.DjInformation' (0x115da8) to 'UINavigationController' (0x3ad405e0).

My appdelegate looks like this

    import UIKit
import CoreData

@UIApplicationMain
class AppDelegate: UIResponder, UIApplicationDelegate {

    var window: UIWindow?

    var centerContainer: MMDrawerController?

    func application(application: UIApplication, didFinishLaunchingWithOptions launchOptions: [NSObject: AnyObject]?) -> Bool {
        // Override point for customization after application launch.

                self.imageArtwork.image = UIImage(data: data)
            }
    })
}
}

These are the two codes that i think should be the cause of the problem. But so far i can't find any way to pas any variables and i will be needing that to complete my app. What am i doing wrong here?

I can really use some help here to get this to work. Maybe my navigation controller is correctly setup. As the first viewcontroller should be embedded in it. But i am not sure i have done that properly.

Thanks for the help.

I have found the solution which was very simple if you know what you should do. When you are using mmdrawer and would like to send over data you could just create a prepareforsegue, but you also need to create a segue with overrides the mmdrawer. I find that you use you use the following just like you would do with prepareforsgue

@IBAction func djInformation(sender: UIButton) {

var artist_label = artistLabel[SelectedSongNumber]

        var centerViewController = self.storyboard?.instantiateViewControllerWithIdentifier("djInformation") as! DjInformation

centerViewController.djINfo = "\(artist_label)"
        var centerNavController = UINavigationController(rootViewController: centerViewController)

        var appDelegate:AppDelegate = UIApplication.sharedApplication().delegate as! AppDelegate

        appDelegate.centerContainer!.centerViewController = centerNavController
        appDelegate.centerContainer!.toggleDrawerSide(MMDrawerSide.Right, animated: true, completion: nil)
    }

so basically what you do in prepareforsegue you can also do in button that is initiating the mmdrawercontroller.

Hope this makes sense and helps some one else. I am in no way a pro and i am not sure if this is proper or more something like a hack. but it fast and easy.
