I'm writing for location information, but requestAlwaysAuthorization() is not available on VisionOS.
I'm not sure if I can't use this method at all, or if there's an alternative way.
If there is a competent developer who knows how to solve it, please reply.
This call is not available in visionOS. Considering none of the location APIs that require "Always" authorization to work at all are also not available in visionOS, what is the use case you have that needs this?
If you have a specific use case and would like this API to be considered for visionOS, you are welcome to file a Feedback report about it.
