How do you create a new document using UIDocumentBrowserViewController in Xcode 9 beta 2?

Question

I am having problems with UIDocumentBrowserViewController Bug in Xcode 9 Beta 2, was working with beta 1.

The symptom is that you can't create a new document, on most pages the + icon is missing or greyed out. On the browse page it is present and not greyed out, but doesn't work.

EG If you start a new Documents project and modify the function below to include the print statement given:

func documentBrowser(_ controller: UIDocumentBrowserViewController, didRequestDocumentCreationWithHandler importHandler: @escaping (URL?, UIDocumentBrowserViewController.ImportMode) -> Void) {
    print("creating document")
    ...

Then the print statement isn't printed when + on browse page is tapped. Testing on iPad Pro 12" (original) with latest iOS 11 beta.

Is this a bug? Am I doing something wrong?

Thanks for any help,

If you think, you're doing the right thing (following Apple's API description), and something doesn't work as expected, you should definitely file a radar: bugreport.apple.com
