You will need to install XCode, and then you will need to launch XCode once in order to agree to the license. After that, see https://www.mathworks.com/matlabcentral/answers/243868-mex-can-t-find-compiler-after-xcode-7-update-r2015b#comment_454130 for the configuration file you need for XCode on Sierra; the location to install to is given in my comment two up from that one.
