Silent Pushes Setup (iOS + APNs + Backend)

When to use

Use this skill when the user asks about:

• Silent/background push notifications on iOS
• APNs device token registration
• aps-environment entitlement errors
• Backend APNs sending (headers, payloads, JWT)
• Widget refresh triggered by pushes
• Debugging push delivery, throttling, or missing pushes

Quick path (agent)

1. Confirm environment
   • Real device vs simulator, Debug vs Release/TestFlight.
   • Bundle ID + Team ID.
   • Backend environment (prod vs dev) and APNs host.
