I was developing VPN client for one of the popular VPN provider in the past for iOS and the solution was quite simple - enable on-demand VPN for 0.0.0.0/0 In this case, iOS will always wait until connection to VPN is established before sending any packets out. Without on-demand, VPN may leak. If I remember correctly, leaks occurred mostly after waking from sleep but before the tunnel had chance to be set up. Or in similar situations. Anyway, on-demand option solved all of them.

This is exactly my experience (have developed multiple iOS vpn apps).

do existing sessions get terminated and restarted through the VPN when you start it? Seems like that's one of the major concerns that the author is raising
