Does the iOS AASA file need to sit on a secure connection? (HTTPS)?

I'm trying to set up a universal link between a site and my app, but I realized that my site is on a non-secured connection (HTTP). If I want to have a universal link to my app, does the AASA request need to be on a secured connection (HTTPS)?

I have found some information about it but it isn't from the apple docs. A conformation about it would be great appreciated!

Yes it does require HTTPS official documentation says:

To protect users’ privacy and security, you should not use HTTP when you need to transport data; instead, use a secure transport protocol such as HTTPS.

Your can validate your AASA file using this tool.
