Can't find ifort in Xcode

[仁义_许_]

The old fortran projects can be compiled successfully, but I can't find the fortran in the compile rules.

I think you have to better specify your question: if you can compile your old code, there obviously is a Fortran compiler (ifort?) on your Mac. What exactly is missing?

Yes，an old ifort is on the Mac. It disappeared after upgrading. Must I setup a new edition such as ifort19?
