Hello
In the past, the documentation and specifically design guidelines were quite clear about the fact that having an exit button was not a good thing, and programmatically exiting the app was prohibited and ground to rejection by the review team.
Looking though the documentation and guidelines nowadays, I cannot find any explicit mention of this. We have a client that want us to add such button on the main menu of an app, and we are looking to hard evidence that this is against standards.
Has Apple stance on this changed ? Or have I missed it in the doc somewhere ?
