Send notifications to users that app is being discontinued I'm having to get a very quick intro to iOS development to support apps for my organization. We would like to post a notification to users of one of our apps that it is being replaced by another. I suppose this would look like a banner when the app is launched. 

What is the right method to make this happen? It's not a push notification (doesn't look like we are enabled for that anyway) but it sounds like it would still require an update to the app. Can anyone help?
I'd address this question to StackOverflow.com. Basically you'll need to create a UIAlert or a UIAlertController and yes, you will need an update to the app.
