This is kind of a strange issue that I discovered when
creating a few projects in XCode 2.2. The precompiled
header file doesn't seem to function. Before, I didn't
need to #import <Cocoa/Cocoa.h> into my files because
it was already in my application's .pch file. Now that
doesn't seem to be the case anymore. I just get lots
of error messages and have to manually #import
<Cocoa/Cocoa.h> to each header file.
If what you say is true, I think I like this change in behaviour - or
at least for the option to have this behaviour. In my opinion I think
that it make sense to make a separation between [1] an implicitly
imported header on the one hand, and [2] precompiled headers on the
other.
We compile our projects for a large number of OS platforms where not
all of them supports PCH. We regularly get / got into troubles where
some developer failed to remember to include a required header in a
source file because it was implicitly included via the PCH file on
Mac OS X. As a consequence, the builds would start failing on the
other platforms.
I'm absolutely no authority on this topic, so take it with a grain of
salt!
