i'm new in swift and first time using Container ViewController to handle multiple controllers.
storyBoard Image
Item Image
But I don't know what is Item here.
I can use segue in containerView Class but not able to use segue in main viewController.
as i'm not aware about "item" as shown in Image
why is there "item", "item1" and "item2" and why 2 segue's has same name as "item" please help me and share information about it.
