Killing a WKWebView content process in the iOS simulator to trigger a webViewWebContentProcessDidTerminate call

trigger webViewWebContentProcessDidTerminate in simulator

# In the command line, find the PID of your simulator process:
ps -p `pgrep launchd_sim`

# or if you have many simulators running:
ps -A | grep launchd_sim

# Find the PID of the WebContent process:
pgrep -P <simulator-pid> 'com.apple.WebKit.WebContent'

# kill it
kill <webcontent-pid>

# or if you want a one-lner:
kill $(pgrep -P $(pgrep launchd_sim) 'com.apple.WebKit.WebContent')

You have no idea how many attempts I've had at trying to fix this for react pages built into our app and I was able to immediately reproduce and solve with this. THANK YOU!!!!
