Does it handle background network requests?

Yes, it includes detailed patterns for configuring and using background URLSessions for persistent downloads and uploads that continue even after the app is terminated.

Is there guidance on avoiding app termination during background work?

Yes, the reference includes critical patterns for properly implementing expiration handlers and calling setTaskCompleted to ensure the system does not terminate your app for exceeding runtime limits.

How do I register background tasks using this skill?

The skill provides the specific code snippets for registering handlers in your AppDelegate or SceneDelegate before the application finishes launching, as required by Apple's guidelines.

What iOS versions are covered in this reference?

It covers background processing from the introduction of BGTaskScheduler in iOS 13 up to the latest features in iOS 26, including BGContinuedProcessingTask.

Mobile Development

Provides a comprehensive API reference and WWDC-aligned code examples for implementing background execution on iOS and xOS platforms.

关于

This skill serves as a specialized knowledge base for iOS developers implementing background tasks using the latest system APIs. It covers everything from standard app refreshes and maintenance tasks to advanced user-initiated background processing introduced in iOS 26. By providing battle-tested implementation patterns for BGTaskScheduler, background URLSessions, and legacy background task completion, it ensures developers can maintain app performance and system compliance while executing critical off-screen operations.
