Create Custom Templates in Xcod

Create Custom Templates in Xcod

There are lost of documents suggesting how to create custom templates in
xcode. But i have some doubts related it.
1) It has a little difficult procedure for creating it , just like modify
template.plist file and other stuffs. So it is feasible to create it if my
template contains so many files , frameworks ?
One another thing that i want to know is ,
2) If we create any template and it contains different modules just like
1) DB classes 2)json classes and by using this template i want to
integrate only db classes in my application . is it possible ? can we give
a selection for that ? select db classes or select json or some other.
Thanks in advance.
