What platforms are supported by this SharePlay skill?

This skill provides patterns for iOS, macOS, tvOS, and visionOS, specifically targeting modern Apple frameworks and Swift 6.3+.

When should I use GroupSessionJournal instead of GroupSessionMessenger?

Use GroupSessionMessenger for small, real-time state updates. Use GroupSessionJournal for large data transfers like images or files that exceed the messenger's size limits.

Does this skill help with late-joining participants?

Yes, it includes specific patterns for identifying new participants and sending them the current app state so they are immediately synchronized with the group.

How does this skill handle media synchronization?

It utilizes AVPlaybackCoordinator with AVPlayer to automatically synchronize play, pause, and seek actions across all participants without manual message passing.

What entitlements are required for SharePlay?

You must add the 'com.apple.developer.group-session' entitlement to your app and set 'NSSupportsGroupActivities' in your Info.plist for iOS 17+ features.

Implement shared real-time experiences and media synchronization in Apple platform apps using GroupActivities and SharePlay.

This skill provides comprehensive guidance for developers building collaborative iOS, macOS, tvOS, and visionOS applications using the GroupActivities framework. It simplifies the implementation of SharePlay, enabling real-time features like synchronized media playback via AVPlaybackCoordinator, high-frequency state updates with GroupSessionMessenger, and large file transfers using GroupSessionJournal. Designed for Swift 6.3 and iOS 26+, it helps developers manage complex session lifecycles, handle late-joining participants, and avoid common pitfalls like session leaks or missing synchronization triggers.
