Initial visionOS support

[rivera-ernesto]

Goals :soccer:

Make the library code-compatible with visionOS 1.0.0

Implementation Details :construction:

It simply uses the same code path for iOS and visionOS.

Thank you for your PR!

I didn't test it on visionOS yet so I'm very excited to see someone using it for the new device 😄

Does reusing the iOS color palette make sense for you? Or, in the other hand, do you think it would be better to create a specific one?
