To run a task in the background when the app is not active, you can leverage several features discussed in the WWDC sessions.
Location Authorization
In the session What’s new in location authorization, it is explained that CoreLocation can keep track of ongoing tasks even if the app is terminated or suspended. This is particularly useful for tasks like tracking a workout. CoreLocation will resume or relaunch the app into the background when new information is ready for delivery and the app's authorization allows it.
App Intents
In the session Design App Intents for system experiences, it is recommended to create app intents that support live activities, audio playback, or recording. These intents can run in the background, making it possible to perform tasks without requiring further in-app action.
Summary
- CoreLocation: Use CoreLocation to manage tasks that need to continue running in the background, such as tracking a workout. CoreLocation will handle the app's lifecycle and ensure tasks resume when necessary.
- App Intents: Create app intents for tasks that can be performed in the background, such as live activities or audio playback.
