Hi, wondering if IOS supports WebTransport (HTTP/3) yet? If so, where can I find information on implementing it in my app?

Hey there! I'm thrilled about the latest from WWDC24. I'm particularly keen on a feature announced for the HomeKit ecosystem called "Hands-free unlock". I'm eager to learn more about how this feature operates and how I can integrate it into my locks and access control systems. Could anyone please provide more details on how it works and how to implement it? P.S - I wasn't able to find any information about this in the IOS 18 Developer release notes.

I am trying to use MapKit JS in Tauri and Flutter desktop apps but I can‘t because if I want the key not to expire I have to whitelist a domain but my apps don't run on the web and therefore don't have a valid domain.
