Updated my Apple Watch Ultra to watchOS 9.5.2 last night and this morning, Xcode is now unable to download the symbols for it. Same issue happened when watchOS 9.5.1. was released (see https://developer.apple.com/forums/thread/730663). The error message, as before, is "Failed with HTTP status 403: Forbidden".
i would give it a day or so, sometimes it takes them a little bit to the the symbols up. We usually go through this every release.
Looks like it's working now.
Hello, I also encountered the same issue, xcode14.3.1 cannot compile watchOS9.5.2. Have you resolved your issue?
