To schedule reliable iOS background tasks with BGTaskScheduler, you must register task identifiers in Info.plist, schedule the task during app launch, and implement handlers with proper expiration handling to ensure tasks run reliably and are cancellable.

BGAppRefreshTask and BGProcessingTask are iOS background execution modes managed by BGTaskScheduler. This skill provides robust patterns for both, covering registration, scheduling, expiration handling, and ensuring accurate task completion signaling for each type.

Bridging BGTaskScheduler expiration to Swift concurrency involves mapping the expiration handler to cooperative cancellation in Swift structured concurrency, ensuring long-running work is cancellable and progress reporting is maintained throughout the task lifecycle.

iOS background processing tasks often fail due to non-compliant Info.plist identifiers, missing task registration at app launch, or failing to call setTaskCompleted. This skill ensures compliance and accurate task completion signaling across all code paths.

Testing BGTaskScheduler background tasks requires simulating scheduling, expiration handling, and completion scenarios. This skill provides best practices for testing background tasks, handling silent pushes, and ensuring tasks complete in all code paths.

Yes, iOS background processing works with Swift 6 structured concurrency by bridging BGTaskScheduler expiration handlers to cooperative cancellation, enabling progress reporting for long-running work and ensuring tasks are reliably cancellable.
