Observing the same with previews, targeting iOS. Missing ”/usr/lib/swift/libswiftWebKit.dylib“. Though this file is really not present in this location. The problem occurs in previews only, normal builds are OK.

visionOS 2.4 is even worse, completely useless. Works OK only for the first minute after installation. Craziest part is that Xcode 16.3 don't see visionOS lower than 2.4, so there's no roll back and visionOS development is basically not possible. Though, obviously no one cares about visionOS.

Seeing the same issue, no visible reason. The scheme clearly exists, project was never renamed, in archive section it has the right scheme selected; though it shows a warning 'The scheme ... may only exist locally...'
