What is this zero link issue?
That's not an issue, that's a feature. ZeroLink is an Xcode
feature that was designed to speed up launch time when developing
large projects. It's enabled in the standard Debug build
configuration. The difficulty with it is that because of how it
works, the resulting application can't run on any machine other
than the one it was built on. [1] The upshot is that you somehow
need to turn ZeroLink off. There are a few different ways to do
that: you could build using the Release configuration, which
doesn't use it; you could uncheck "Allow ZeroLink" in the Build
menu; or you could disable it in your Debug configuration.
I always just switch to Deployment, is there something wrong with that?

[1] ZeroLink "links" your application not by combining the various
object files, but rather by creating a launcher that knows where to
find them when needed at run-time. Therefore, your "application"
file doesn't contain your code, but rather references to it
elsewhere on disk, and therefore won't run if it can't find them.
It would work if you copied the relevant parts of the build
directory as well, but you didn't know to do that, now, did you?
