How to Change the Selection Color in an NSTextView Using SwiftUI

Creating custom text views using SwiftUI can enhance the user experience, especially when it comes to how text is displayed and interacted with. One common requirement is to customize the selection color in an NSTextView to align with your app’s branding or visual theme. In this article, we'll go through a straightforward approach on how to change the selection color of an NSTextView in SwiftUI.

Understanding the Problem

When implementing selectable text in SwiftUI using NSViewRepresentable, developers often encounter issues with customizing the appearance of selection highlights. The confusion can arise over which properties of NSTextView allow modification and how to apply them effectively. Specifically, changes to the selectedTextAttributes property may not yield the desired results if the text view is not configured properly to handle selection events.

Step-by-Step Solution

To change the selection color in an NSTextView while using SwiftUI, you need to implement a custom view that includes the necessary configurations. Let’s break it down into a few simple steps.

1. Create a Custom NSTextView

You'll start by creating a struct that conforms to NSViewRepresentable. This struct will be responsible for creating and configuring the NSTextView.

2. Customize Selected Text Attributes

In the makeNSView function, you have the ability to set the selection colors using selectedTextAttributes. Here’s what the code does:

Foreground Color: This defines the color of the selected text itself. In our example, it's set to NSColor.systemGreen.

Background Color: This defines the color of the highlight behind the selected text, which we've set to NSColor.systemRed.

3. Use Your Custom View in SwiftUI

Now that the custom NSTextView is created, you can use it in your SwiftUI views like this:

Conclusion

Integrating a custom NSTextView within SwiftUI to change the selection color is straightforward once you understand how to set the relevant attributes. By following the steps outlined above, you can create an engaging interface that allows users to interact with text selections in a visually appealing way.

Final Thoughts

Customizing selection colors not only enhances the user interface of your SwiftUI applications but also improves overall usability. Experiment with different colors to find what works best for your app, ensuring a cohesive look and feel. Happy coding!
