Get Parent ViewController from within embedded child UIViewController

Question

How do I get a reference to the parent UIViewController from within a controller which is embedded in it using a Container View?

I want to access the Parent from within the Child.

Answer 1

When you add view controller in container view it is added as child view controller

You can access child it like following way

  if let yourVC:YourViewController = self.childViewControllers.first(where: {$0 is yourVC:YourViewController}) as? YourViewController {
        // Here you got it 

    }

You can access Parent with parent property of viewController

  if let parent = self.navigationController?.parent as? ParentControllerType {

     // Do what you want with the parent.

   }
