SwiftUI's WebKit allows custom URL scheme handlers for local resources.
This involves creating a handler that conforms to the URLSchemeHandler protocol.
The reply method in this handler receives a URLRequest and should return an async sequence.
This sequence yields URLResponse and Data, or throws an error.
First, extract the URL from the request and validate its scheme.
Then, determine the file, mime type, and load the data from the app bundle.
Construct a URLResponse with details like mime type and data length.
Finally, yield the response and data, or an error if issues occur.
Register this custom handler in a WebPage.Configuration using the desired URL scheme.
Use the configured WebPage in a WebView and load the custom URL to display local content.
