Select UITabbarItem from embedded Container UIViewController

Question

How can I select programmatically a UITabbarController item from a UISegment from other ViewController?

ViewcontrollerA has a UISegmentControl and a ContainerView

UITabbarControllerB is embedded in the ContainerView from ViewControllerA and has itself two ViewControllers VCItemA and VCItemB.

Now the problem is, I can't change the VCItem from UITabbarControllerB via the SegmentControl from UIViewcontrollerA.

You can try inside ViewcontrollerA ( Swift)

if let tab = self.children.first as? UITabbarControllerB {
   tab.selectedIndex = // 0 or 1
}

( Objective - C )

if ([self.childViewController.firstObject isKindOfClass:UITabbarControllerB.self])
  UITabbarControllerB* tab = (UITabbarControllerB*) self.childViewController.firstObject;
  tab.selectedIndex = // 0 or 1
}
