i see one developer mentioned that this was resolved in Xcode 12 beta 6. i thought i had noticed that this was resolved in Xcode 12 beta 6 … but seems to have resurfaced in Xcode 12 GM . i noticed that the release id associated with Xcode 12 beta 6 (12A8189n) is newer than the current Xcode 12 GM (12A7208) . it may be worth checking if Xcode 12.2 beta once again resolves the issue (i have not yet installed it).

Just had this problem with iOS 17 beta 7 … followed the later instructions to remove my SIM card and then quickly get past the wifi choice before it connected with my WiFi network. there was a dialog about needing to use wifi to continue, but i got past it. all good, because i didn't / don't have Siri set up.
