How to Easily Popup a Sheet in SwiftUI with WKWebView

In today's post, we will tackle a common issue when working with the WKWebView in SwiftUI: how to handle link navigation without leaving the current view. Instead of moving to a new screen, we’ll learn how to display the link's information in a convenient popup sheet. This solution enhances user experience while browsing content within your app.

Understanding the Problem

When you're building a SwiftUI application that displays HTML content using WKWebView, you might want to provide users with a seamless way to view linked content. Typically, when users click a link, it navigates away from the current interface to show the new page. This can feel jarring, especially if your goal is to maintain context for the user.

Our Objective

We want to create a function to:

Detect when a link is clicked in the WKWebView.

Display the link's associated information in a popup sheet.

Allow users to return easily to the original view once they are done exploring the link.

Step-by-Step Solution

Let’s break down the solution into sections for clarity:

1. Update the HTMLView

We start by modifying the HTMLView structure to include a navigation handler. This handler will be used to manage link actions.

2. Coordinator Implementation

Now, we’ll implement the Coordinator to handle navigation decisions.

3. Using the DetailsView

Next, we modify the DetailsView to manage the state of the URL request that we want to display.

4. (Optional) Wrapping URLRequest

To help SwiftUI handle state better, you can create a wrapper for URLRequest. This allows us to treat it as an identifiable element when presenting the sheet.

Conclusion

By following these steps, you can effectively manage navigation within a WKWebView and allow users to view linked content in a popup sheet form instead of navigating away from the current screen. This approach provides a much smoother user experience, making your app more user-friendly and engaging.

Try integrating this method into your own SwiftUI app, and see how it enhances your interface. Happy coding!
