If you are using NavigationController to push one ViewController to other then for navigate back you have to use Pop like this,

self.navigationController?.popViewController(animated: true)

and if you are using Modal Controller to present another Controller then for navigate back you have to use dismiss like this,

dismiss(animated: true, completion: nil)

Let me know in case of any queries.

You are presenting the view controller not pushing it. To come back to the controller, write down the below controller:-

dismiss(animated: true, completion: nil)
