When reading how to prepare network for iCloud Private Relay, I can see: "Private Relay protects users’ web browsing in Safari, DNS resolution queries, and insecure http app traffic." "iCloud Private Relay uses QUIC" But QUIC (HTTP/3) is experimental in Safari 15. Why?

When I use a NSData field, should I compress data before setting value or is it done by encryption? If data is encrypted first, compression after that is generally more complicated. Or perhaps compression gain is not really significant and I don't need to care about it?

Hey, Apple!Did you plan a TestFlight localization for testers?It's a very big problem to distribute beta apps to non-english users.The process is already difficult (download an app, to download another app, and connect with Apple ID).If it's in english, it's nearly impossible.Thanks,
