Xamarin.IOS Build Host troubleshooting

XamarinBuildIOSChecks.cmd

## Just as sanity check, make sure that the OS sees that the Xamarin.iOS Build Host app is running

In Terminal.app:

$ ps -x | grep Xamarin\.iOS | grep Applications
2627 ?? 0:02.17 /Applications/Xamarin.iOS Build Host.app/Contents/MacOS/Xamarin.iOS Build Host

## Use `lsof` to check if the Xamarin.iOS Build Host app `launchd` item is listening on port 5000

In Terminal.app:

$ lsof -i -P | grep -i listen
launchd 164 bzagaeski 39u IPv4 0x85c33c8d4928413f 0t0 TCP *:5000 (LISTEN)
launchd 164 bzagaeski 41u IPv6 0x85c33c8d4446ca5f 0t0 TCP *:5000 (LISTEN)

## Try re-running the `launchctl` command to unload + reload the launch daemon, just to be thorough

In Terminal.app:

$ launchctl unload -w /Library/LaunchAgents/com.xamarin.mtvs.buildserver.plist

$ lsof -i -P | grep -i listen

$ launchctl load -w -F /Library/LaunchAgents/com.xamarin.mtvs.buildserver.plist

$ lsof -i -P | grep -i listen
launchd 164 bzagaeski 41u IPv4 0x85c33c8d4763c13f 0t0 TCP *:5000 (LISTEN)
launchd 164 bzagaeski 43u IPv6 0x85c33c8d4446ca5f 0t0 TCP *:5000 (LISTEN)

$ launchctl list | grep xamarin
- 0 com.xamarin.mtvs.buildserver
2627 - com.xamarin.mtvs.buildservergui.65680
