Answer 1

You can't get the state of any WKInterface UI element like buttons (WKInterfaceButton) label (WKInterfaceLabel) etc. I think this is designed by Apple like this because it involve under the hood communication between the extension running on your iOS device & the watch App. To save this overhead there are no getters and the extension should keep track of the state change (it is the one that can change the state).
