background-processing

To schedule background tasks on iOS, you register and submit BGAppRefreshTask, BGProcessingTask, or BGContinuedProcessingTask requests via the BackgroundTasks framework, configuring conditions like network connectivity and charging state in your Info.plist.

Background URLSession manages downloads and uploads that persist even if the iOS app is terminated. The system handles the data transfer in the background and wakes the app to deliver the completion results once the network operations finish.

Yes, silent push notifications can trigger background data fetches on iOS. The system receives the push payload and wakes your app in the background, allowing you to execute URLSession data transfers or update content before the user opens the app.

BGAppRefreshTask is used for short tasks requiring brief execution time to update app content, while BGProcessingTask handles longer operations like data processing or maintenance, often requiring external power and specific network conditions.

Handle background task expiration by implementing the task's expiration handler to clean up operations before the system terminates the app. You can simulate expiration and task scheduling during iOS debugging using Xcode command line arguments.

Yes, configuring Info.plist is required to register background tasks on iOS. You must declare the permitted background task identifiers in the Info.plist file so the system recognizes and authorizes the scheduled BGAppRefreshTask or BGProcessingTask requests.
