I bought the Intel Fortran Compiler because of its integration to Xcode (macOS).
With version iFort 19.1 and Xcode 11, I can still compile and export "Command line tools". However using the "Legacy Build System" seems to introduce problems with applications mixing languages. I succeeded to "Run" from Xcode an application with several Schemes (C, Cocoa, Fortran, shell script) but failed to export it to an Archive : "Command /usr/local/bin/ifort-18.104.22.168 failed with exit code 15", etc. May be I made a mistake but other error messages such as "option '-target x86_64-apple-macos10.15' not supported" clearly indicates that the iFort integration to Xcode is outdated.
I read the post of Ronald W Green (Blackbelt) Thu, 02/06/2020 - 13:16 on this forum " "We are planning to remove Xcode* integration capabilities within our Intel® Parallel Studio XE 2020 Composer Edition for Fortran for macOS*."
I am not sure I will continue buying the Intel compiler !
