Assuming you want to drop the argument (value) after --xcode-dir as well:
#!/usr/bin/env bash
args=("$@")
myargs=()
nextarg=-1
for ((i=0; i<$#; i++)) {
if [ $nextarg == $i ]; then continue; fi
case ${args[$i]} in
--xcode-dir) nextarg=$((i+1)) ;;
*) myargs+="${args[$i]} "
esac
}
echo $myargs
./remove_xcode --xcode-dir foo --bar baz
--bar baz
