Why can't MEX find a supported compiler in MATLAB R2016a after I upgraded to Xcode 9.4.1?

I installed Xcode 9.4.1 on my Mac and tried to use MEX. I receive the following error at the MATLAB command prompt:
>> mex -setup
Error using mex
No supported compiler or SDK was found. For options, visit
http://www.mathworks.com/support/compilers/R2016a/maci64.html
Why does MATLAB not recognize the Xcode 9.4.1 installation on my Mac?
The problem is that I can use it before, but after I have ran the code 'ruby -e "$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)" < /dev/null 2> /dev/null' to install GSL, I can not use mex on Matlab normally anymore.
Please help me!

Because Xcode 9 is not explicitly mentioned in the list of supported compilers for R2016a, you have no guarantee it will work. Apparently it doesn't, so either you'll have to upgrade Matlab to one that will work with the new version of Xcode, or you'll have to downgrade Xcode again to 7.x.
