I have an app that lets users copy files into it's document directory for the app to import and worked fine in IOS 12.4.1 for IPad. It has both necessary permissioning keys set <key>LSRequiresIPhoneOS</key> <true/> <key>LSSupportsOpeningDocumentsInPlace</key> <true/>Unfortunately on the IPad simulator in IOS 13.1, it doesn't allow Apple's Files app to copy files into the directory (giving the dialog warning "The Operation can't be completed. Couldn't communicate with a helper application.") and fails when trying to export files out, with the error:[DocumentManager] Failed to create FPSandboxingURLWrapper for file:///Users/ronkashden/Library/Developer/CoreSimulator/Devices/9CF7F5C0-7399-4595-A974-BD2D99DFBEDF/data/Containers/Data/Application/C07A1ED6-9849-4DC5-B404-2EE387D57CBA/Library/Application%20Support/investmentAppDB.sqlite.
