I can’t seem to get the simulator to boot up on my machine. It hung in the “verifying package” part, so I force quit the Xcode Beta, and couldn’t get that screen to pop back up, even after “uninstalling” the beta.
Tldr: create a new visionOS app from the menu, it'll prompt to download the support files correctly.
Had a similar issue after doing the Xcode 15 beta 2 download with both iOS 17 and visionOS 1 simulator checked.
When creating a new visionOS App it would tell me that I'm missing the device/simulator support and prompted to install it.
After confirming this it would show a download for a build that ended in xxxxxxxg instead of xxxxxxxf as was part of the download, so I assume that part was updated in the background and now is no longer the correct reference.
Anyone have any ideas?
