I'm trying to make ViewController present after Modal dismiss
let storyboard = UIStoryboard(name: "Main", bundle: nil)
let chatRoomVC = storyboard.instantiateViewController(withIdentifier: "ChatRoomVCId") as! ChatRoomVC
chatRoomVC.hidesBottomBarWhenPushed = true
chatRoomVC.passValue = passValue
self.dismiss(animated: true, completion: {
self.present(chatRoomVC, animated: true, completion: nil)
})
But it will return "whose view is not in the window hierarchy!" maybe it's present a view after the controller dismissed

When present from "Controller_A" to "Controller_B"-> present it like given below
--- View Controller A ---
self.navigationController?.present(Controller_B, animated: true, completion: nil)
When you want to dismiss "Controller_B" and present "Controller_C" using Navigation controller
--- View Controller B ---
let presenController : UINavigationController = self.presentingViewController as! UINavigationController
presentingController.dismiss(animated: true, completion: {
presenController.pushViewController(Controller_C, animated: true)
})

You are using self. It means you are dismissing the current view controller. It should be the parent view controller who will present a new view controller.

Notice the self
in self.present
, what you are doing, is basically tell the vc that you are dismissing to present a new vc, thats wrong way to do, the correct way is tell it's PARENT vc to present a new vc, by using delegate/unwind to call the parent vc to present new vc
