How to Use Two Segues from One Element in UIKit with Swift: A Step-by-Step Guide

When developing iOS applications, efficiently managing segues is crucial for creating a smooth user experience. If you’ve ever faced the challenge of wanting to use two segues from one element in a UITableView, then you’re in the right place! In this post, we’ll address the common problem of setting up two distinct segues from a single row and provide a step-by-step solution.

The Problem at Hand

Imagine you have a UITableViewController where every row has two actions:

Tapping a row directs the user to one view controller.

Swiping a row offers an action that leads to a different view controller.

The catch is that UIKit typically allows only one segue to be directly associated with each UI element in a storyboard. Many developers fall into a trap where the prepare(for segue:sender:) function is not called as expected when using performSegue.

This can create confusion, especially when you need to pass data to different view controllers based on user actions. So, how can you overcome this?

A Structured Solution

Understanding prepare(for segue:sender:)

The prepare(for segue:sender:) method only works properly when a segue is triggered directly from a table row. When using performSegue from an action, the selected row is not set, leading to unexpected behaviors.

Step 1: Adjusting Your Swipe Action Configurations

Modify your trailingSwipeActionsConfigurationForRowAt method like this:

Step 2: Updating prepare(for segue:sender:)

Next, modify your prepare(for segue:sender:) method to better handle the incoming sender. Here’s how:

Step 3: Avoiding Unnecessary Segues

When you want better control over instance management, consider deleting the segues from your storyboard altogether and adopting a programmatically driven approach to presenting view controllers.

For Example:

Replace your existing segue calls with programmatic instantiation like this:

This approach allows for greater flexibility and control without the limitations of storyboard segues.

Conclusion

Using two segues from a single element in UIKit requires careful management of your methods and sometimes a shift away from storyboard-driven segues. By ensuring you pass the correct sender type and embracing programmatic view controller management, you'll create a more intuitive experience for your users.

With this guide, you should now be equipped with the knowledge to effectively manage segues and improve your application’s usability. Happy coding!
