The Fastlane assembly on MacOS fell on the following error:
xcode-select: error: tool 'agvtool' requires Xcode, but active developer directory '/Library/Developer/CommandLineTools' is a command line tools instance
Solution:
Make sure that Xcode is installed, and then run the following command:
sudo xcode-select -s /Applications/Xcode.app/Contents/Developer
