I'm currently using Xcode 15 beta 5, and while I have no problem pairing with an Apple TV 4K 3rd gen running latest tvOS 17, it gets stuck afterwards trying to connect to it. In the devices window, it just says "Connecting to Apple TV — Xcode will continue when the operation completes."
I get the same message when trying to deploy an app. If I leave it long enough, it switches to: "Previous preparation error: A connection to this device could not be established.. Timed out attempting to establish tunnel to the device."
This happened in the original Xcode 15 beta as well. I've also tried connecting to another Apple TV running tvOS 17 (4K 1st gen), which had the same thing happen. It connected okay to an Apple TV HD running 16.5 however.
Non-beta Xcode 14 appears to connect okay to the tvOS 17 devices, but it can't do much with them. Any ideas?
