Summary:
This is a duplicate of radar #38500183

After presenting view controller from UIDocumentBrowserViewController the presented view controller’s isBeingPresented property is still set to false.


Steps to Reproduce:
See attached playground.

Expected Results:
isBeingPresented should be set to true, which is the case when presenting form UIViewController.

Actual Results:
isBeingPresented is set to false.

Version:
11.2

Notes:
This is an unexpected inconsistency. There’s no way to detect that the controller is already being presented by inspecting it’s state. If you need to prevent from presenting the controller twice you need to track the state.
