Command Line Tool - Error - xcrun: error: unable to find utility "xcodebuild", not a developer tool or in PATH

Question

I solved that problem by setting the Command Line Tools in Xcode. Go to:

Xcode > Preferences > Locations

And select the command line tool from the dropdown. If you have only one version of Xcode installed, there should be only one option. If you have several versions of Xcode, then you must choose the one you need.

Update (added image for reference)

The simplest fix is from CLI:

sudo xcode-select -s /Applications/Xcode.app/Contents/Developer

(this should be path to your Xcode.app)

By the way this can happen even if you have only one version of Xcode . It happens when you instal homebrew before the first Xcode installation (which makes sense because you may want to install Xcode through mas install 497799835 and mas needs homebrew).
