ios - Pass data to two tab bar view controllers -

i trying pass data first view controller 2 other view controllers, in tab bar, have been struggling trying through prepareforsegue. code @ moment:

override func prepareforsegue(segue: uistoryboardsegue, sender: anyobject?) {     if (segue.identifier == "showrides") {         var tabcontroller = segue.destinationviewcontroller as! uitabbarcontroller         var navcontroller = tabcontroller.viewcontrollers![0] as! uinavigationcontroller         var destcontroller = navcontroller.viewcontrollers[0] as! initalviewcontroller          destcontroller.parkpassed = parkselected          var tabcontroller1 = segue.destinationviewcontroller as! uitabbarcontroller         var navcontroller1 = tabcontroller.viewcontrollers![1] as! uinavigationcontroller         var destcontroller1 = navcontroller.viewcontrollers[1] as! mapviewcontroller          destcontroller1.parkpassed = parkselected     } } 

i have tried pass data first view controller first tab, , second tab, didn't have success either.

anyone have suggestions? current code returns error: fatal error: array index out of range on second last line.

thanks!

figured out. had change code this:

        var tabcontroller1 = segue.destinationviewcontroller as! uitabbarcontroller         var navcontroller1 = tabcontroller1.viewcontrollers![1] as! uinavigationcontroller         var destcontroller1 = navcontroller1.viewcontrollers[0] as! mapviewcontroller          destcontroller1.parkpassed = parkselected 

i had stupidly forgot change of variable names, , had change index of nav controller's view controller.
