Using appium-xcuitest-driver

Hey all, apologies if this is a bad question I’m just getting stuck with it. I’ve just picked up a framework written by someone else who left my organisation and Im trying to figure out how to swap the driver from the default IOS driver to the new appium-xcuitest-driver since we want to move to ios 10 and xcode 8.

I’m not seeing caps being set anywhere. It seems they are just launching from a command like appium --command-timeout 600 --app "+ appPath+udid" --platform-version "+platformver

Theres no Appium.txt file anywhere I can see.

I’m very new to appium so I have no idea where I would set the caps. is there a better way to be launching the server?
