identifierForVendor is changed for the asme same vendor and same device when OS got updated from 15.6 to 16.0 beta 4. Ideally it should not be happening. We are using the below API to get the UUID.
UIDevice.current.identifierForVendor?.uuidString
Need help in resolving the issue. Adding the sample app.
