I'm pretty thoroughly confused about the relationships and connections between targets, build phases, and build configurations. They all seem like subtly different names for the same thing.

They're not really the same thing. I assume you have a copy of the Xcode documentation?


A target is basically a group of build phases. A target builds a binary. A build configuration is a named group of build settings for a target. Build settings are things like warning flags, optimization levels, et.c.

Take a deep breath! You're new to the tool, and bound to feel a bit confused. It will all make a lot more sense in a couple of days!

All I'm trying to do is to maintain debug and non-debug versions of my code.

You don't have to do anything to get that. It's set up automatically when you create a new project.


Perhaps I should say that you shouldn't be able to add multiple copies of a file to the same phase of the same build configuration of the same target. That's apparently what was happening to me. I didn't mess with targets or phases, or whatnot. All I did was drag files from the Finder into the project window and somehow I got into a state where Xcode was adding a single file to the link chain twice. Unfortunately I can't reproduce it now so I don't know exactly what I did.

I think that there is some sort of bug in Xcode that allows for this to happen. In Xcode 2.2 they added a warning for this so that you could see when it happens (at build time). We had to fix this problem in almost all of our projects. I assumes that the error had sneaked in with some earlier version of Xcode, but perhaps the problem is still there.


Not that it's a particularly serious bug - it's easy enough to spot and correct.
