ios_tcpdump.sh

# Attach iOS device to Mac and create virtual network
# Use real iOS UUID instead placeholder
# It is possible to get UUID with iTunes: just click on `Serial number` field
rvictl -s UUID
# Returns `Starting device UUID [SUCCEEDED] with interface rviX`

# Start dumping traffic
# Use real name of virtual network instead `rviX`
# To stop use `ctrl + C`
sudo tcpdump -i rviX -w ~/ios.pcap

# Remove virtual network
rvictl -x UUID
