Obj C -> Swift conversion

While I expect that most people are not bulk converting

existing Obj C code to Swift, I'm curious to know what

strategies people who have attempted that may have employed.

I haven't found a utility that can properly parse Obj C

into a token tree and intelligently spit out Swift, and I certainly

don't want to spend my own time crafting a YACC file etc.

Assuming such a serious attempt at building a converter

has not succeeded, my guess is that the default

strategy people've used is something like writing a shell script

that uses sed to reduce excessive cutting/pasting and text

replacements. Is this indeed the case?

e.g.

s/- (void)/ func/

s/@end/ }/

Etc...

Cheers.
