Adding a Notification Service Extension to a Rork App — Rich Push, Encrypted Payloads, and Dynamic Rewriting
Wiring a Notification Service Extension into a Rork-built iOS app — image attachments, end-to-end encrypted payloads, and dynamic APNs payload rewriting — with working Swift code and the production pitfalls that bit me along the way.
When Push Notifications Reach Only Some Users — A Delivery-Reliability and Diagnosis Design for Rork (Expo) Apps
A design for diagnosing why push notifications reach only some users in a Rork-generated Expo app, by splitting send-to-display into stages and measuring delivery to close the gap. Covers stale-token cleanup, recording APNs/FCM failure codes, priority and message type, and a per-user triage procedure, with implementation.
Updating Live Activities Remotely: Putting Live Lock Screen Info on a Rork App
A practical design for updating Live Activities remotely through APNs so the Lock Screen and Dynamic Island stay current even when your app is closed. Covers push-to-start vs update tokens, the content-state payload, stale-date and the update budget, and bridging from Expo, with working code and the issues I hit in production.
