[swift-users] Pure Swift, cross platform way to open, read/write files?

Thanks for that blog post... perhaps I wasn't clear in what my actual
question was. Let me restate:

Obviously I can use Glibc on Linux to open a file and read it. And since
there is no Glibc on OS X, is there some other way that would be both CROSS
PLATFORM and done purely in swift instead of relying on some external C

I've taken a cursory look at some of the early swift resources and didn't
see anything that mentioned how to open a file using JUST Native Swift
code... One would surely think that a programing language as nifty and cool
as Swift would have a easy way to read files. Maybe its obvious and I just
am missing it.

But at the same time I get your point just use #if #else #endif to
conditional import / call functions... but coding like that doesn't seem
vary fun... reminds me of looking a C code that was meant to be compiled on
different processor architectures. :-(
