Implement, review, or improve Live Activities and Dynamic Island experiences in iOS apps using ActivityKit. Use when building real-time updating widgets for the Lock Screen and Dynamic Island — delivery tracking, sports scores, ride-sharing status, workout timers, media playback, or any time-sensitive information that updates in real time. Also use when working with ActivityKit, ActivityAttributes, Activity lifecycle (request/update/end), Dynamic Island layouts (compact/minimal/expanded), push-to-update Live Activities, or Lock Screen live widgets.

# ActivityKit Build real-time, glanceable experiences on the Lock Screen, Dynamic Island, StandBy, CarPlay, and a paired Mac using ActivityKit. Patterns target iOS 26+ with Swift 6.3, backward-compatible to iOS 16.1 unless noted. See [references/activitykit-patterns.md](references/activitykit-patterns.md) for complete code patterns including push payload formats, concurrent activities, state observation, and testing. ## Contents - [Workflow](#workflow) - [ActivityAttributes Definition](#activityattributes-definition) - [Activity Lifecycle](#activity-lifecycle) - [Lock Screen Presentation](#lock-screen-presentation) - [Dynamic Island](#dynamic-island) - [Push-to-Update](#push-to-update) - [iOS 26 Additions](#ios-26-additions) - [Common Mistakes](#common-mistakes) - [Review Checklist](#review-checklist) - [References](#references) ## Workflow ### 1. Create a new Live Activity 1. Add `NSSupportsLiveActivities = YES` to the host app's Info.plist. 2. Define an `ActivityAttributes` struct with a nested `ContentState`. 3. Create an `ActivityConfiguration` in the widget bundle with Lock Screen content and Dynamic Island closures. 4. Start the activity with `Activity.request(attributes:content:pushType:)`. 5. Update with `activity.update(_:)` and end with `activity.end(_:dismissalPolicy:)`. 6. Forward push tokens to your server for remote updates. ### 2. Review existing Live Activity code Run through the Review Checklist at the end of this document. ## ActivityAttributes
