Where do I get it? Is it in a jar? Is it available for download somewhere?
Edit:
I tried
npm install appium-ios-driver
and
sudo npm install appium-ios-driver
Both failed with:
npm WARN enoent ENOENT: no such file or directory, open ‘/package.json’
npm WARN !invalid#1 No description
npm WARN !invalid#1 No repository field.
npm WARN !invalid#1 No README data
npm WARN !invalid#1 No license field.
