To implement Live Activities, you must define ActivityAttributes and Codable ContentState models, then use ActivityContent to request, update, and safely end activities across all code paths. This enables real-time, glanceable status updates on the Lock Screen and Dynamic Island.

You can update Live Activities remotely by configuring APNs push-to-update workflows with correct token handling and payload formatting. This requires starting the activity with the correct pushType and managing state updates via activity.update.

Handling stale content states in ActivityKit requires modeling correct Codable ContentState and applying proper dismissal policies when activities are updated or ended. This ensures outdated UI is safely dismissed across Lock Screen and Dynamic Island layouts.

Designing Dynamic Island UIs involves building distinct compact, minimal, and expanded layouts while managing limited space. You must configure these layouts alongside Lock Screen widgets using current ActivityKit APIs.

Yes, modern ActivityKit APIs support scheduled activities, ActivityStyle configurations, paired Mac and CarPlay behavior, and channel-based push. These platform additions allow broader real-time status updates beyond standard iOS surfaces.

Live Activities fail to end safely when completion or failure paths are not explicitly handled. You must ensure activities are dismissed using correct dismissal policies and ActivityContent for every request, update, and end operation.
