Getting exception Command 'xcrun' is not found. Is it installed? while executing using eclipse

The problem

When I am trying to start the appium server programmatically and then instantiate the IOSDriver, I am getting the Exception Command 'xcrun' is not found. Is it installed?

• Node.js version (unless using Appium.app|exe):v12.6.0
• Npm or Yarn package manager: Npm

I am not getting this issue when I am starting the appium server manually and instantiating the IOSDriver

Start at ComcastTestMain.startTestMain (line 1138) and beforeTest_startTestMain (line 955), comparing the programmatic Appium startup with the manual startup described in the issue. Reproduce the IOSDriver initialization on the listed macOS, Appium, Node.js, and iOS versions; done means the programmatic path no longer reports that xcrun is unavailable, or the required limitation is documented.
