Thanks for the suggestion. However, my question was specifically about intercepting AJAX API calls, not regular page navigations. The webView(_:decidePolicyFor:preferences:decisionHandler:) method only helps intercept navigation-level URL loads, whereas AJAX/XHR requests happen internally via JavaScript and don’t trigger navigation actions. So, I'm looking for a way to inspect or intercept XHR / fetch API calls initiated inside the WebView, which unfortunately cannot be handled using WKNavigationDelegate.
