This document summarizes features for building document-based apps in iOS 11, including UIDocumentBrowserViewController, FileProvider, and settings in the app's Info.plist. It provides an overview of how to set up document support and export/import uniform type identifiers to share documents between apps and extensions. Code samples and demo apps are shown for browsing and opening documents from other apps and cloud services using the new iOS 11 APIs.
