What is background processing in iOS?
Unlike Android, iOS has restrictions for the use of background processing in an attempt of improving battery life and user experience. When your apps enter to background mode, it's time developers get out of control of their app. How and when your app gets a chance to execute your task totally depends on the system.
How long iOS apps can run in background?
For most apps, five seconds is enough to perform any crucial tasks, but if you need more time, you can ask UIKit to extend your app's runtime. You extend your app's runtime by calling the beginBackgroundTask(withName:expirationHandler:) method. Calling this method gives you extra time to perform important tasks.
How to use iOS background tasks framework to keep your iOS app content up to date?
Use the BackgroundTasks framework to keep your app content up to date and run tasks requiring minutes to complete while your app is in the background. Longer tasks can optionally require a powered device and network connectivity. Register launch handlers for tasks when the app launches and schedule them as required.
