We don't have an xrOS slice in our xcframework deliverable as of Sentry 8.15.2.

Support for VisionOS was added in Carthage 0.39.1 to add xrOS slices to xcframeworks.

The VisionOS SDK is still only delivered in the latest Xcode beta (15.1b3 released 14 Nov) and not the latest GA release version (15.0.1), and we don't currently use betas in our release job. (In fact, we're still running Xcode 14.3 for building the xcframework: #3411.) UPDATE: there is movement on this front, now that Xcode 15.2 is out with GA support for VisionPro/xrOS, and GitHub has a prerelease actions runner with the requisite OS/toolchains: #3410 (comment)

Part of us upgrading to Xcode 15.2 in CI will overlap with #3329

After we support VisionOS for Carthage, we need to update the docs getsentry/sentry-docs#8496.
