I was developing Android App that could be opened by url link sent to email. The domain exist but the path not (ex. google.com/abcdefgh1234). Im not an owner of the website so putting AASA file there is not possible. The link also contained jwt with some info that I was handling in the app. I wanted to do the same on ios but what I found, URL schemes doesn't support http and Universal Links need special file on that website. Is there a way to handle this on iOS?
You can check custom URL scheme https://developer.apple.com/documentation/xcode/allowing_apps_and_websites_to_link_to_your_content/defining_a_custom_url_scheme_for_your_app
It will work without adding special file to the server. You need only a special link and after a tap on it, you will be redirected to that app (if it exists on your phone). Maybe this is what are you looking for
