Unable to launch WebDriverAgent because of xcodebuild failure exit Code 127

Question

I am getting this error when trying to run iOS appium test. Seems I cant find much on exit code 127 failure. Any help would be great. Thanks

Answer 1

The issue may be related to not using the latest cartage version, try running:

brew upgrade carthage

Then re-run the failing command directly in terminal:

cd /Applications/Appium.app/Contents/Resources/app/node_modules/appium/node_modules/appium-webdriveragent/Scripts/
carthage-wrapper.sh bootstrap --platform iOS\,tvOS
