SwiftUI TapGesture Not Working with NavigationLink in List on iOS

If you're developing an app in SwiftUI and have ever encountered issues with TapGesture not triggering the navigation to a new view within a List, you're not alone. This can be frustrating, especially when trying to execute actions after a link is tapped but before navigating to the new view, such as a TextEditor. In this post, we'll explore the problem and provide a practical solution.

The Problem

Using TapGesture in conjunction with a NavigationLink is a common way to execute code on tap actions. For example, you might want to update a state variable or perform some logging. Here’s a simplified version of what the issue looks like:

In theory, the above code would run the tap gesture's action and then navigate to the specified destination. However, when this code is placed within a List, the navigation does not take place. The tap gesture is registered, but the transition to your intended view fails.

The Solution

To ensure that both the tap action and the navigation work in harmony, consider using ForEach instead of List. As you'll see in the example below, ForEach provides similar functionality but resolves the navigation issue you've encountered.

Updated Code Example

Here’s how you can modify your original code:

Key Changes Explained

Using ForEach: We replaced the List with ForEach. This approach enables individual tap gestures to execute their associated code without interrupting the navigation process.

Flexibility and Functionality: This maintains the same presentation while allowing flexible tap gesture handling. It also avoids potential bugs with TextEditor that could arise from loading states.

Conclusion

While using NavigationLink within a List might seem straightforward, the interaction with TapGesture can lead to unexpected behavior. Leveraging ForEach as a workaround not only solves your immediate problem but also grants you greater control over your navigation flow in SwiftUI.

Try this approach in your own applications, and you'll likely find an enhanced experience for your users. Happy coding!
