How to Fix Safari in-App Browser Opening with Delay in iOS 16 Using SwiftUI

Creating a smooth and engaging user experience is critical in mobile app development. However, as developers, we often encounter issues that detract from this experience. One such problem is the Safari in-app browser in iOS 16 opening with a delay or sometimes resulting in a black screen. In this guide, we'll delve into this problem and explore a simple, effective solution using Swift and SwiftUI.

The Problem: Safari In-App Browser Delays

As of iOS 16, when we attempt to open a URL within our app using SwiftUI, the browser can behave inconsistently. An example code snippet would look like this:

While this code successfully launches Safari, the user experience could be improved - often, it opens with a delay of over five seconds or displays a black screen first, which can be frustrating.

The Solution: Using Main Dispatch Queue

From my experience addressing this issue, I found that performing the Safari opening action on the main queue resolves these delays. The main dispatch queue ensures that high-priority tasks like user interface updates execute promptly.

Implementing the Solution

Here’s how you can modify your SwiftUI code to utilize the main queue effectively:

Wrap your URL launch in a DispatchQueue.main.async block:

This ensures that the action of opening Safari takes place on the main thread, thereby interrupting any lag caused by other processes in the app.

Example Code

Here's an updated version of your original code that integrates this solution:

Conclusion

Utilizing the main dispatch queue can quickly resolve the issues of delays and inconsistencies when opening the Safari in-app browser within iOS 16 using SwiftUI. This adjustment not only enhances performance but also improves user experience significantly.

By implementing this simple change, your application can provide a smoother and more reliable experience when interacting with web content. If you're facing similar issues, give this solution a try, and you might see immediate improvements!
