What system limitations may arise when performing tasks in the background?

In iOS, there are the following limitations when performing tasks in the background:

• Limited execution time: The app can run in the background only for a limited time (usually a few minutes), after which the system suspends or terminates it.
• Limited access to resources: Background access to CPU, network, and other resources is restricted to conserve energy.
• Background task restrictions: Some tasks (e.g., content updates, geolocation, audio) require special permissions or the use of Background Modes.
• System priority: If the system experiences resource shortages, background tasks may be interrupted.

For long-running background operations, it is recommended to use Background Fetch, Background Processing Tasks, or Push Notifications to wake up the app.
