Multi watch interface with WatchConnectivity Context

Question

I create an iPhone application (with a view) / Watch (with interface) that displays speed, distance and a timer with a Play / Pause, Stop and Clear.

I used to share WatchConnectivity Application Context data between (Send and receipt of Context). Everything works so far, but I would add another page / interfaces on which exchanges Watch the Context with the iPhone and there I do not know at all how.

My Interface Storyboard

If I turn on the Session 2 interfaces, information is lost

Here is my current code, I want to toggle the display of labels TimeLabel, distanceLabel Label and speed on the second interface

I'd suggest having your UIApplicationDelegate and ExtensionDelegate create an instance of a new object you make that is the WCSessionDelegate. This object will persist incoming data to disk, and post notifications that the backing data store has been updated. Then each of the UI components can monitor for these notifications and update their UIs as appropriate.
