Programmatically go back to previous ViewController in Swift

Question

I send the user over to a page on a button click. This page is a UITableViewController. Now if the user taps on a cell, I would like to push him back to the previous page. I thought about something like `self.performSegue("back")....` but this seems to be a bad idea. What is the correct way to do it?

Accepted Answer

Swift 3:

If you want to go back to the previous view controller

```
_ = navigationController?.popViewController(animated: true)
```

If you want to go back to the root view controller

```
_ = navigationController?.popToRootViewController(animated: true)
```

If you are not using a navigation controller then pls use the below code.

```
self.dismiss(animated: true, completion: nil)
```

animation value you can set according to your requirement.
