Surprisingly, I found that there is a homebrew formula for xfig; I then installed xfig by:

brew install xfig

But, I cannot start xfig:

~$ xfig
Warning: locale not supported by Xlib, locale set to C
Warning: X locale modifiers not supported, using default
Warning: Cannot convert string "-*-times-medium-r-normal--16-*-*-*-*-*-*-*,-*-*-medium-r-normal--16-*-*-*-*-*-*-*,*--16-*" to type FontSet
Warning: Unable to load any usable fontset
Warning: Unable to load any usable fontset
[1]    70074 segmentation fault  xfig

What is going wrong? I am using MacOS Sonoma 14.1, Apple Silicon, and XQuartz is running.

This issue has been reported in Homebrew issue Segmentation fault when executing xfig on apple silicon #160515. It appears the issue needs to be fixed with the formula itself (or its fontconfig dependency formula).
