 Background tasks defined by the app.

 When adding new background tasks, don't forget to update `BGTaskSchedulerPermittedIdentifiers` key in `Info.plist` by adding a task identifier
 using the following pattern:

 ```
 $(APPLICATION_IDENTIFIER).<TaskName>
 ```

 Note that `<TaskName>` is capitalized in plist, but the label for enum case should start with a lowercase letter.
