I believe you need to install the ideviceinstaller prior to using Appium to perform automation tests on iOS. Quoting from here the following should help. Try running on your terminal :
ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null
// Wait for the command to finish.
Run: brew install ideviceinstaller
