Same issue here, but only happens occasionally. I think it might have to do with the use of type(of:, at least that's where it crashes in our app. Hoping this will be fixed soon.

Hello, So I think there has been a kind of misunderstanding. I assume @technomage was talking about an app that runs in compatibility mode, so it's not specifically compiled for visionOS. Under these circumstances it is probably expected behaviour to pretend not to be run on visionOS to not break old code that is checking for iOS vs other. I had the chance to test on a real device now and as long as I don't add visionOS as a supported architecture the app will always run in compatibility mode and pretend to be iOS. Since compiling everything for visionOS is not an option right now with multiple dependencies being incompatible we have to resort to a workaround as suggested by https://medium.com/@timonus/low-hanging-fruit-for-ios-apps-running-on-visionos-08a85db0fb31 (I did not test this) or https://stackoverflow.com/a/77962734 (works)
