I want to enable file sharing, just like in this guide: https://developer.xamarin.com/guides/ios/application_fundamentals/working_with_the_file_system/
but, as others have pointed out, the Info.plist editor in Visual Studio is limited. People have suggested editing the raw xml, but I don't know the magic lines to add.
I guessed <key>UIFileSharingEnabled</key> from the guide, but I don't know what the next line, the "value" line, is supposed to be. I've tried <boolean>yes</boolean> and <bool>yes</bool>, attempting to imitate the guide, but apparently there is no "boolean" or "bool" in the xml parser. I've also tried <string>yes</string> but the app still doesn't show up in iTunes. Not having the line simply results in a build error.
