Appium Won't Run from xcodebuild failure - Missing XCUICoordinate.h

If you've been getting this error on OSX Appium when running tests for iOS:

Error: Unable to launch WebDriverAgent because of xcodebuild failure: "ENOENT: no such file or directory, open '/Applications/'".

Try running:

cd /Applications/ ; npm install


This should install the missing requirements and fix your issue. Hopefully this dependancy step gets patched soon.
