Conditional compilation – easy way !!

I achieved this by adding a #define in .pch file for each project.

and do #import based on that definition using #ifdef

This is the pretty cool and easy way  if your are sharing single source code set across multiple target/build/project

Just make use of different .pch file for different builds.

You want to create <n>  number of .pch file for <n> targets. Assign corresponding  .pch file for each target’s info
