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)…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# 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 an `ActivityConfiguration` in the widget bundle with Lock Screen content and Dynamic Island closures. …

How to install
mdr add jordancoin/ios-skills-collection/activitykit@sha256:994053d4a9fa9b8dThe line at the top of this page pins the label git:20260329.893209f, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
