Setting up Xcode for ROS

[dilukamdp]

Thanks to this script and all the related discussions in issues, I managed to install ROS on Mac and it is working fine. Now, I'm wondering whether anyone tried to setup Xcode with ROS in macOS High Sierra ? I tried to create an Xcode project using: catkin_make -G"Xcode" however it ends up with

make: *** No targets specified and no makefile found. Stop.
Invoking "make -j4 -l4" failed

and doesn't open up the ROS project as eclipse does. If anyone has done that I appreciate if you can kindly share. I'm sorry if this is not relevant, and kindly remove if that is the case. Many thanks anyways.
