Why is my background task not running immediately?

The system determines the best time to run background tasks based on usage patterns, battery life, and resource availability; you can only suggest an 'earliestBeginDate'.

What is the new iOS 26+ BGContinuedProcessingTask?

It is a specialized task for work initiated in the foreground that continues in the background, featuring system-managed progress reporting via Live Activities.

How do I prevent 'notPermitted' errors in BGTaskScheduler?

You must register every task identifier in your app's Info.plist under the 'BGTaskSchedulerPermittedIdentifiers' key and enable the appropriate Background Modes.

Does this skill work with SwiftUI Apps?

Yes, it includes specific patterns for registering background task handlers within the SwiftUI App initializer and handling background events efficiently.

Why is expiration handling critical for iOS background tasks?

The system can reclaim resources at any time. Failing to call the completion handler or ignoring the expiration handler will cause the system to penalize your app's future background runtime.

Mobile Development

Implements robust background task scheduling and execution for modern iOS apps using the BackgroundTasks framework and Swift 6.

This skill provides expert guidance and standardized implementation patterns for managing background work on iOS 26+ using the BackgroundTasks framework. It helps developers correctly register, schedule, and execute short-lived refreshes, long-running maintenance tasks, and the modern iOS 26+ Continued Processing tasks with Live Activity integration. By emphasizing correct Info.plist configuration and precise expiration handling, this skill ensures apps maintain high performance without incurring system penalties or battery drain.
