Is there any document or video come out of Apple to explain the Support HTTP3 acquiescently on iOS16?

Answer 1

If you're using URLSession, you don't need to change your app since iOS 15 and macOS Monterey ship with HTTP/3 enabled by default. Once you enable HTTP/3 on your server, you're good to go.
