Does codesigning run before or after explicit "postbuild" entries in your gyp
file? (Does chrome/ios use explicit postbuilds?)

It runs after -- very last step.

Hm, that's annoying :-/

Maybe we should change the emulation api to be like:

postbuilds = self.xcode_settings.AddImplicitPostbuilds(postbuilds, ...)

and then the strip and codesign steps could both be added there (the first in
front, the second in the back). Having two calls to add implicit postbuilds is
somewhat lame

Be sure to have tests that check that codesigning runs after regular postbuilds.
