Schedule and execute background work on iOS using BGTaskScheduler. Use when registering BGAppRefreshTask for short background fetches, BGProcessingTask for long-running maintenance, BGContinuedProcessingTask (iOS 26+) for foreground-started work that continues in background, background URLSession downloads, or background push notifications. Covers Info.plist configuration, expiration handling, task completion, and debugging with simulated launches.
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.

## Info.plist Configuration
Every task identifier **must** be declared in `Info.plist` under
`BGTaskSchedulerPermittedIdentifiers`, or `submit(_:)` throws
`BGTaskScheduler.Error.Code.notPermitted`.
```xml
<key>BGTaskSchedulerPermittedIdentifiers</key>
<array>
<string>com.example.app.refresh</string>
<string>com.example.app.db-cleanup</string>
<string>com.example.app.export</string>
</array>
```
Also enable the required `UIBackgroundModes`:

How to install
mdr add jordancoin/ios-skills-collection/background-processing@sha256:45283ce969fb7c3bThe 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.
