Platforms Affected

• iOS
• Android (did not test - possibly?)
• Web (does not affect web)

Current Behavior

When loading the build from a sveltekit application in hash routing mode, the application appears to continuously reload the webview - never initializing sveltekit:

(reproduction project provided)

npm install
npx vite build
npx cap sync
npx cap open ios

xcode output: (webview loads about every second)

⚡️  Loading app at capacitor://localhost...
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
⚡️  WebView loaded
...

This does not occur when in server mode from vite, nor in web.

Expected Behavior

It should behave identically to when in server mode or web

Marking it as a bug because it works if we load capacitor://localhost/ instead of capacitor://localhost (notice the / at the end), but looks like a sveltekit bug to me not handling well urls with non standard schemes such as capacitor

I don't think we would be changing the url to load to add the / as it could cause other issues to other users, but maybe add a configuration option to conditionally add it.

@jcesarmobile Thank you for the quick discovery of the root cause. What would be the idiomatic way to add the trailing slash to capacitor currently, given that configuration option does not yet exist?
