Answer 1

The accepted answer to this question is no longer correct:

Starting with iOS 7, UIKit exposes the function UIAccessibilityRequestGuidedAccessSession as public API.

I don’t know, but can very well imagine that this function existed as private API dating back to iOS 6, where the guided access feature was introduced.

Note that for this method to have any effect, the device in question must be supervised using MDM, and the ID of the app you want to use this API must be included in the device management profile deployed to it.
