I'm sure someone has probably already done this, but in case not...
I've created some project templates for creating MAX and MSP
externals in Xcode, available here:
From when I was getting started I found the recommended method of
copying the examples and renaming, etc a bit cumbersome and
confusing. Hopefully the templates will make life easier for a least
a couple of people other than myself!
I haven't been able to try the templates with Xcode 3, but 2.5 and
lower all seem to work fine.
I'm open to comments, suggestions etc, so give them a try and let me
know what you think.
