Configuring Group Activities
Leverage FaceTime infrastructure to create coordinated experiences users can share.
Overview
Use Group Activities to bring your app’s users together to enjoy new and exciting shared experiences that are built atop SharePlay and the FaceTime infrastructure. For example, a karaoke app might offer karaoke parties where several participants take part simultaneously from their own devices.
Represent shareable activities by creating objects that conform to the GroupActivity protocol and, after a shared activity begins, use GroupSession to synchronize that activity across participants’ devices.
Add the Group Activities capability to your target
Follow the steps in Add a capability to add the capability to your app’s target, making sure you select the Group Activities capability from Xcode’s Capabilities library. This capability is available on all platforms except watchOS, and you must add it to an app target — Group Activities aren’t available in widgets, extensions, or App Clips.

After you add the Group Activities capability, Xcode updates your target’s entitlements file to include the com.apple.developer.group-session entitlement. If Xcode automatically manages the signing of your app, it also enables Group Activities for your app’s App ID.
When you add the Group Activities capability, there are additional steps you must complete before your app’s users can start experiencing shared activities; for more information on these steps, see Defining your app’s SharePlay activities and Joining and managing a shared activity.
