XCode is actually pretty horrible as IDEs go. It doesn't even have a solid plugin architecture. When will you see vi/vim plugin for XCode? That makes it pretty much a toy and unusable.
Honestly, XCode is pretty horrible when compared to even Eclipse.
Not entirely true. Xcode does have a plugin model; just explore the Xcode developer install and you'll find it is entirely built up via plugins. Unfortunately, Apple have chosen not to document it or make it public.
is this really an argument against what super_mario says? when he says it doesnt have a plugin architecture of course he means extendibility by everyone.
