Help loading local index.html on iOS using Asset protocol

[lukeyreyno]

I'm trying to create a Webview Window on iOS using the following code:

let html_path = format!("asset://cache/{}/index.html", app_name);
                    tauri::WebviewWindowBuilder::new(
                        app,
                        "main",
                        WebviewUrl::External(Url::parse(&html_path)?),
                    )
                    .build()?

When I unzip -l on the .ipa from npm run tauri ios build, I get the following path:
Payload/loc8-royale.app/cache/loc8-royale/index.html

I have set up the asset protocol in tauri.conf.json as so:

"security": {
      "csp": null,
      "assetProtocol": {
        "enable": true,
        "scope": ["**/*"]
      }
    }

I keep getting No such file or directory (os error 2) when I inspect at the safari devtools.
It's trying to fetch URL: asset://cache/loc8-royale/index.html

If I try to fetch using http://asset.localhost, I get errors from ATS.

Please let me know what I might be going missing with my setup.
