Guys last 2 to 3 day I am trying to run an example project for J2OBJC conversion. First I faced issue for the j2objc command not found, fixed this issue by adding the path to the /etc/paths file. Now I am facing an issue like J2OBJC_HOME path not defined correctly.
`/bin/sh -c if\ [\ !\ -f\ \"${J2OBJC_HOME}/j2objc\"\ ];\ then\ echo\ \"J2OBJC_HOME\ not\ correctly\ defined\ in\ Settings.xcconfig,\ currently\ set\ to\ \'${J2OBJC_HOME}\'\";\ exit\ 1;\ fi;\ \"${J2OBJC_HOME}/j2objc\"\ -d\ ${DERIVED_FILES_DIR}\ -sourcepath\ \"${PROJECT_DIR}/Classes\"\ --no-package-directories\ -use-arc\ --prefix\ Othello.Engine=JOE\ -g\ ${INPUT_FILE_PATH};

Guys, please help me to fix the above, anyone already faces such issue.
Thanks in advance.
Like most "*_HOME" settings, it's something you need to specify (like JAVA_HOME, KOTLIN_HOME, GROOVY_HOME, etc.). Edit Settings.xconfig and set J2OBJC_HOME to the same path you added to /etc/paths.
The next problem is that j2objc does not run with a Java 9 JDK (coming soon). The good news is that multiple JDKs can be installed on your Mac, and the j2objc script will pick the latest Java 8 JDK installed, regardless of whether the Java 9 JDK is the default. Go to Oracle's Java SE Downloads page, get the latest Java 8 JDK and install it.
