Programmatically go back to previous ViewController in Swift

🔄 Going Back to Previous ViewController in Swift

Are you struggling to find the correct way to programmatically go back to the previous ViewController in Swift? You're not alone! Many developers face this common issue when building iOS apps. But don't worry, we've got you covered with easy solutions and a compelling call-to-action at the end. So let's dive in! 💪

The Problem

Imagine you have a button in your app that takes the user to a new page, which happens to be a UITableViewController. Now, when the user taps on a cell in the table, you want to seamlessly navigate them back to the previous page. 😕

The Solution

Using the performSegue method might seem like a good idea at first, but it's not the correct approach for going back to the previous ViewController. Instead, we'll introduce you to two simple and efficient ways to achieve this:

1. Using the Navigation Controller

If your UITableViewController is embedded within a UINavigationController, you can take advantage of the navigation stack to go back. 🚗🔙

In your table view delegate method, when a cell is tapped, you can use the following code to navigate back to the previous ViewController:

navigationController?.popViewController(animated: true)

By calling the popViewController(animated:) method on the navigation controller, you safely go back to the previous ViewController, preserving the navigation history and animation.

2. Dismissing the Current ViewController

If you don't have a navigation controller, or you want more control over the dismissal animation, you can use the UIViewController's dismiss(animated:completion:) method. 📱🔚

In your table view delegate method, when a cell is tapped, you can use the following code to dismiss the current ViewController:

dismiss(animated: true, completion: nil)

This will nicely dismiss the current ViewController and take the user back to the previous screen. You can also set up a completion block to perform additional actions after the dismissal if needed.

Conclusion

You've learned the correct ways to programmatically go back to the previous ViewController in Swift. Whether you're using a navigation controller or need to dismiss the current ViewController, these solutions will work like a charm! 🎉

Now it's your turn to implement these approaches in your app and provide a seamless user experience. Share your thoughts and experiences in the comments below. We'd love to hear from you! 💬❤️
