Background Processing

Overview

Background execution is a privilege, not a right. iOS limits background work for battery and UX. Core principle: treat tasks as discretionary jobs; you request time, the system decides when or whether to run.

Key insight: Most "task never runs" issues come from registration errors or misunderstanding the seven scheduling factors.

This skill focuses on task mechanics: reliable launch, execution, and completion.

Requirements: iOS 13+ (BGTaskScheduler), iOS 26+ (BGContinuedProcessingTask), Xcode 15+
