Hi everyone !
As you can see, I just published some new templates on github that should fix all the current issues (among other fixes).
The installation is the same, you just need to uninstall the old ones manually (from /Library/Developer/Xcode/Templates).
Have a look at
this readme for more information.
Note that the tutorial will be updated when 2.0 is officially released.
If anything doesn't work as expected, please tell me.
Happy Coding !
EDIT:
If you want to use universal project, set CMAKE_OSX_ARCHITECTURES to "i386;x86_64".
