Summary: Since UIDocumentBrowserViewController is required to be the rootViewController and there’s no delegate when the initial loading of documents finishes, apps are more or less forced to use an empty, white/black (depending on browserUserInterfaceStyle) Launch Storyboard to have a decent animation when switching from the Launch Storyboard to the actual app UI. Steps to Reproduce: 1. Open the attached DocumentBrowser-based app 2. observe the cut between the Launch Storyboard and the UIDocumentBrowserViewController loading state Expected Results: It’s possible to customize the loading state of UIDocumentBrowserViewController Actual Results: The loading state is an empty white screen with a UIActivityIndicatorView in the middle Version: iOS 11b1 Notes:
