there's two ways to return/back to the previous ViewController :

1. First case : if you used : self.navigationController?.pushViewController(yourViewController, animated: true) in this case you need to use self.navigationController?.popViewController(animated: true)
2. Second case : if you used : self.present(yourViewController, animated: true, completion: nil) in this case you need to use self.dismiss(animated: true, completion: nil)

In the first case , be sure that you embedded your ViewController to a navigationController in your storyboard
