It seems like if you have a number of swap chains, to render to swap chain n you must have rendered to swap chain n - 1 at least once first. Is this correct? I have a bug in my program which indicates this is true.

hi,

no I don't really think this is true. I have variable number of swap chains in my code, and render to them quite randomly (sometimes I even disable rendering to some of them). The swap chains are independent from each other I think.
What is your problem that has driven you to this conclusion?
