background-processing

# Background Processing Generator Generate production background processing infrastructure -- BGTaskScheduler for periodic refresh and long-running tasks, background URLSession for downloads/uploads that survive app termination, and silent push handling for server-triggered updates. ## When This Skill Activates Use this skill when the user: - Asks to "add background processing" or "background tasks" - Mentions "BGTaskScheduler" or "BGAppRefreshTask" or "BGProcessingTask" - Wants "background refresh" or "periodic background updates" - Asks about "background downloads" or "background uploads" - Mentions "silent push" or "content-available push notifications" - Wants data to sync or update while the app is in the background - Asks about "background fetch" or "background execution" ## Pre-Generation Checks ### 1. Project Context Detection - [ ] Check deployment target (BGTaskScheduler requires iOS 13+) - [ ] Check Swift version (requires Swift 5.9+) - [ ] Check for @Observable support (iOS 17+ / macOS 14+) - [ ] Identify source file locations ### 2. Existing Background Task Detection Search for existing background task code: ``` Glob: **/*BackgroundTask*.swift, **/*BGTask*.swift, **/*BackgroundDownload*.swift Grep: "BGTaskScheduler" or "BGAppRefreshTask" or "BGProcessingTask" or "backgroundSession" ``` If existing background code found: - Ask if user wants to replace or augment it - If augmenting, identify what is missing and generate only those pieces ### 3.
