iOS Question IOS life cycle question

[DickD]

I am trying to understand the IOS life cycle as it seems very different than android. On android a service would continue to run and send notifications to the user even if they left the app and decided to play candy crush or angry birds for a while.

But in testing the conversion of my app to IOS it looks like once you leave the app (i.e. press HOME to start another app) the app is effectively dead until you relaunch it. Is this the case? Is there anything you can do to keep a background app running?

There are specific things that you app can do in the background.

You can receive push notifications while your app is in the background (or not running at all).

Not sure I understand that. If I'm reading section 7 of the Beginnger's Guide correctly then an app is killed shortly after going to the background. I assume that means pressing the home button. If the app was killed what can it do? Does this have something to do with Firebase (i.e. push notifications)?

Push notifications is an OS feature. As I wrote it works when the app is not running.

Other things that you can do in the background:
