I was able to solve this error without installing the full Xcode application. You must, however, have xcode command line tools installed.
From here:
$ cd /usr/bin$ sudo mv xcodebuild xcodebuild.orig(A backup just in case)$ vim xcodebuild- Paste the following:
#!/bin/bash
if [[ $1 == '-version' ]]; then
echo "Xcode 10.2.1"
echo "Build version 10E1001"
else
/usr/bin/xcodebuild.bak $@
fi
$ sudo chmod +x xcodebuild
