 Orbot uses tun2socks to connect the Android VPN interface to the tor SOCKS
 port.  iCepa/OnionBrowser on iOS uses tun2tor for a similar setup.  Both
 of these approaches have issues since they involve setting up network
 sockets.  Since both Android and iOS now both load tor as a shared
 library, the best possible interface would be for the tor shared library
 to directly provide the TUN interface on both platforms.  It could be an
 optional feature like the HTTP CONNECT feature.
