Access func and variables of UIViewController in other UiViewController

Question

My app has navigational control i have 2 UIViewController. viewCon1 is initial view controller.

I then Pushed the viewCon2 in navigational control. Now i want to access variables and func of viewCon1 in viewCon2 without static logic.

I used static func logic to get Self of viewCon1 i.e. WK_DshBrd

let dashBoardObj = WK_DshBrd.getDasBoardObject() as! WK_DshBrd
            dashBoardObj.unReadMsgsCaseArr?.append(caseNo)

But i get following error on runtime

    Could not cast value of type 'Watch_Extension.WK_DshBrd' (0x7f1e0) to 'Watch_Extension.WK_DshBrd' (0x7ed78).

How can i cast it or achieve required functioanlity in alternative way?

You can use prepareForSegue method in your first controller. There you can retrieve second view controller like this:

let controller = segue.destinationViewController as! SecondViewController
controller.data = "test" //PASS DATA HERE

Eventually you can even pass reference to first view controller here, but it's not recommended.

I cannot use Segue, my requirement is i need to push viewcontroller later. Not through Segue – Hassy Nov 13 '15 at 09:46
So how are you switching to the second view controller. If you are using instantiateViewControllerWithIdentifier you can also pass data here. – Makalele Nov 13 '15 at 09:50
I am developing in WatchKit and using pushControllerWithName("ViewCon2",context:nil) to push InterfaceController – Hassy Nov 13 '15 at 09:52
Hmm I'm not familiar with WatchKit. Also you can try accessing initial view controller (if it's the one you need) using self.window.rootViewController property. Are you using a storyboard? – Makalele Nov 13 '15 at 09:54
Yes i am using a storyboard – Hassy Nov 13 '15 at 09:55
check you my edited answer – Makalele Nov 13 '15 at 09:57
I am using same thing for passing data, the thing is i have to pass data later on not while pushing controller. – Hassy Nov 13 '15 at 10:01
You can give your view controller as context then. – Makalele Nov 13 '15 at 10:04
