The usual suggestion is to apply in reverse order of travel.

I had a similar case, visiting London then going to France on a holiday. I applied for UK visa first before applying for schengen visa to French embassy. Everything went smooth. I was asked though in the french embassy to make sure i had proper visa when visiting London. I showed the lady that I already have the proper visit visa so that was it. I got both UK visa and Schengen visa on a holiday to France.
