how do i see the output of fprintf calls I make from my c native plugin in xcode console?

I would like to see the outputs of my (f)printf function calls that i make from my unity C native plugin in Xcode. I am using Unity2021.2.7f1 and xcode 13.2.1 on macbookpro M1 max running macos 12.1.

In my plugin I tried calls like:

 ::fprintf( stderr, "hello\n") ;
 ::fflush( stderr);
 
 // I have also tried stdout and also  just using  fprintf ( without::) also tried printf and ::printf

I remember this working few years back on older unity versions and older mac.

Also I read and remembered that these outputs can also go to a log file somewhere. I tried to look for files that would look like ~/Library/Unity/Debug.log but could not find. Either way I would much prefer to see the outputs in xcode console window.

I tried the option in xcode scheme to use terminal as console instead of xcode but then xcode would launch a terminal window but not be able to launch unity.
