in second line im having following error: 

uiviewcontroller not have member named "viewcontrollers"

anybody me?

thanks

you trying access property viewcontrollers of type uiviewcontroller, doesn't have. viewcontrollers property on uitabbarcontroller, viewcontrollers returns array of uiviewcontroller.

cast viewcontrollers array of uitabbarcontroller (or item extract) access it's viewcontroller property.

like this:

let barviewcontrollers = self.tabbarcontroller?.viewcontrollers as! [uitabbarcontroller]

or this:

let listviewcontroller = (barviewcontrollers![2] as! uitabbarcontroller).viewcontrollers![0] as! dbviewcontroller
