Ok I got it finally working. Download the visionOS pkg from the developer site Stop Xcode 15 Beta 2 Open the PKG and open the folders until you get the xrOS 1.0.simruntime file Navigate to the same folder /Library/Developer/CoreSimulator/Profiles/Runtimes Copy the file to the local folder Start Xcode 15 Beta 2 A progress will show that it verifies that package In my case it gave an error that it could not verify the developer (hopefully you are lucky and it's done here) Go the the file in /Library/Developer/CoreSimulator/Profiles/Runtimes open the package (right click / show package content) and run the file "update_dyld_sim_shared_cache" it allows you to click open if you right click the file and than select open Start Xcode 15 Beta 2 It's working.... well it did for me. Hope this helps...?

Same here... rebooted, redownloaded.... can't get visionOS to work in the simulator. Even when downloaded separately from developer site and manually copied to the Runtimes folder... still no joy.

Same here with UIKit, AppDelegate and WKWebView. Points to class AppDelegate in the warning... no other information.

Yes I don't feel it's even on "a" list on Apple's side. Nothing has changed and the problem remains. Never got any replies from the bug reports we sent in either.

We had an other go at this in macOS 12.2.1 today. But still no joy. The official bug report is still open, but the problem still remains. This worked in macOS 10.15.4 (confirmed by an other SO user), and hasn't worked since macOS 11 en still not in macOS 12. How is it that we get no response at all to a serious bug like this? It's not like there are easy workarounds for doing a task like this...? We really want custom filters on a CALayer back here! And since a builtin CIFilter does work it should not be this hard, that it takes over 8 months and 2 macOS versions to figure out what is wrong??

While going through some screenshots of the crash I actually found one more that says something about Screen layout change with no seed change. Since I can't edit the original question anymore, or upload an image I'm not sure how to get you the full log details.

Any ideas as too pinpointing this type of issues? Since we can't actively replicate it but it happens random like 2/3 times a day while working on our application. How ever once the crash occurs we have no idea how to figure our who started the issue. We have seen these messages before the crash. Not sure they always happen though. Will check the next time it happens: 2021-09-28 15:53:06.503135+0200 ****[48028:857651] [] [15:53:06.503] FPSupport_GetDisplayRefreshInformation signalled err=-12780 (kCMBaseObjectError_ParamErr) (CGDisplayModeGetRefreshRate returned 0) at FigPlayerSupport.m:3198 2021-09-28 15:53:06.548090+0200 ****[48028:857658] [] [15:53:06.548] customVideoCompositor_CopyProperty signalled err=-12784 (kFigBaseObjectError_PropertyNotFound) (unrecognised property) at FigVideoCompositor_Custom.c:581
