WatchOS2 Watch Connectivity still require app groups in capabilities?

Question

In the old WatchOS1, app groups was required for any sharing of data.

In WatchOS2, Watch Connectivity replaces the old framework for communication.

I was wondering if app groups is still needed?

Answer 1

No, app groups will not help with sharing data between your iOS app and the WatchKit extension. You might however need to use an app group between the WatchKit app and the WatchKit extension as some of the media playing APIs seem to run in the app process.
