Hi Kelly
It depends on the manufacturer - Dragon are actually unusual among the majors (along with Revell Germany - understandably) in not including swastikas in at least some form or other. When they've sometimes sought my advice on Luftwaffe colour schemes I have pointed this out, but they still err on the side of "political correctness" - however, to be fair, I don't know what constraints they're working under. What I find harder to understand is how the Finnish Hakaristi swastika has been tarred with the same brush when it had nothing to do with Nazism and yet is still censored on some kit releases - that really is ill-informed political correctness gone mad (in my opinion)...
All the best
