Question on ensuring flush completes when called before background / termination

[james-ff]

Hello,

My team are looking at increasing the flush limit for events sent up to segment. We also want to ensure that, on app background and close, all events are flushed regardless of limit.

We've explored this option described by Apple to ensure that flush commands have enough time to execute:
https://developer.apple.com/documentation/uikit/app_and_environment/scenes/preparing_your_ui_to_run_in_the_background/extending_your_app_s_background_execution_time

With this approach:

• Is the flush command synchronous?
• Would there be a problem with wrapping .flush command in this closure setup?
• Is Segment handling this concern already such that we do not need to provide this wrapper?

Many Thanks,

James
